5Chapter 1Congratulations on selecting Precise Biometrics’ Fingerprint Identification System! Usingyour fingerprint for identification is an easy and secure way to prove your identity. Pleaseread this chapter before you install and use the system.This chapter includes the following information:• Precise 100 SC – the fingerprint reader• Why use fingerprint technology?• The Precise 100 Family• Icons and conventions IntroductionChapter 1 Introduction
6Precise 100 SC – the Fingerprint ReaderCongratulations – you are about to use the Precise 100 SC for secure, cost-effective andconvenient logon! The Precise 100 SC fingerprint readerThe fingerprint reader includes a sensor for reading fingerprints and a smart card readerfor reading and writing information on smart cards. When you place your finger on thefingerprint reader, the part of the finger that touches the sensor is read. The sensor meas-ures the capacitance in the finger pad, which reveals the pattern of the fingerprint. Thus,a paper copy with a picture of a fingerprint can not grant access to the system. When logging into a system, the read fingerprint is compared to a fingerprint template,i.e. a data file containing information about the fingerprint, stored on a hard disk or on asmart card. If the read fingerprint matches the fingerprint template, the system will grantyou access. If the match is not successful, the system will deny access. It takes less thanone second for the system to compare a read fingerprint with the information in the data-base. All information sent between the fingerprint reader and computer is encrypted formaximum security.If the information is stored on a smart card, you must insert the smart card into the smartcard slot on the fingerprint reader before placing your finger on the sensor. If you do nothave a smart card, your fingerprints are stored on the hard disk, and you will simply enteryour username and place your finger on the fingerprint reader to log into the system.Chapter 1 Introductiondiodefingerprint sensorsmart card slot
7Why Use Fingerprint Technology?In modern society, there is a vast need for secure identification at for instance logon to acomputer network. An unauthorised person who obtains access to computer files consti-tutes a major risk to many companies. In order to prevent unauthorised access, networkusers have previously identified themselves with a password entered together with theusername when logging into a network. The disadvantages of passwords are:• Unreliable identification. An unauthorised person who knows your password can easily access your user account.• A complicated system. In order to increase security, users are regularly asked to change their passwords. This makes it difficult to remember a password.• Users forget their passwords, this increase the administration workload.• Users write down their passwords on notes and store them close to their applications. This can be a serious security hazard.The advantages of fingerprint identification are:• Secure identification. By identifying yourself with your fingerprint, you use a unique “key” to access your user account. All your fingerprints are unique – no person has identical fingerprints.• Simplicity. It is simple to use fingerprints for identification. You do not have to worry about changing or memorising passwords anymore – your fingerprint provides secure identification, year after year.Simply put, with Precise 100 SC, you are identified by who you are, not by what you know!Chapter 1 Introduction

Then continue with the Installing the Fingerprint Identification Softwaresection. NOTE: If you are using a Precise 100 SC with parallel port connector, it is very importantthat the parallel port is set to ECP mode before using the fingerprint reader. Otherwise, thefingerprint reader will not function properly. See Setting the Parallel Port in this chapter. This chapter includes the following information:• Minimum system requirements• Preparing Installation• Setting the parallel port • Connecting the fingerprint reader• Installing the fingerprint identification software• Attaching the fingerprint readerNOTE: In order to log into your domain server account using your fingerprint:• the Precise 100 SC must be installed on your workstation• the Precise 100 SC Server must be installed on the domain server• your fingerprints must be registered by a domain server administrator on the domain serverInstallationChapter 2 Installation
12Minimum System RequirementsIn order to install the software included on the enclosed CD-ROM, your computer mustmeet the following system requirements:• PC with 200 MHz Pentium processor or equivalent• 10 MB hard disk space available• USB port or Parallel port with ECP support and PS/2 keyboard/mouse port• Windows NT Workstation 4.0 operating system, with Service Pack 3 or higher, or Windows 2000.• Mouse or compatible pointing device• CD-ROM drive (unless you are installing the software from a network)• VGA resolution graphics card or higherChapter 2 Installation
13Preparing InstallationThe Precise 100 SC fingerprint reader comes in two versions: Precise 100 SC PAR andPrecise 100 SC USB. The Precise 100 SC PAR communicates with the computer throughthe computer’s parallel port and the keyboard port or mouse port is used to power the fin-gerprint reader. The Precise 100 SC USB communicates with the computer through thecomputer’s USB port.In the following a picture of a parallel connector indicates a sectionrelevant only to Precise 100 SC PAR readers while a picture of aUSB connector indicates a section relevant only to Precise 100 SCUSB readers.If you are a using a Precise 100 SC USB reader you should skip the following two sec-tions and continue with the Installing the Fingerprint Identification Software section. How-ever, if you are using a Precise 100 SC PAR reader, follow the instruction below prior tostarting the installation.Setting the Parallel PortBefore connecting the fingerprint reader, ensure that the parallel port is set to ECP mode.It is very important that the parallel port is set to ECP mode before using the fingerprintreader. Otherwise, the fingerprint reader will not function properly. If you do not knowwhether your computer is in ECP mode (most new computers are), please see thecomputer manual for additional information, or follow the instructions below.1. Access the system setup utility. On most computers, this is done by pressing the F1, F10, Delete or Esc key during system booting – i.e. immediately after the power switch on your computer has been turned on. Keep pressing the key until the system setup, sometimes called the BIOS, appears.2. Find the parallel port mode. Set the port mode to ECP (sometimes called Flexible mode). If you are unable to find the port mode, your computer is probably already in ECP mode.3. Save your changes and exit the system setup utility. If you have problems with the ECP settings, please contact your computer retailer.Chapter 2 InstallationParallel USBChapter 2 Installation
14Connecting the Fingerprint Reader to theComputer1. Turn off the computer.2. Make sure that the parallel port is set to ECP mode.3. Connect the fingerprint reader to the parallel port at the back of the computer by using the connector. Make sure that the connector is secured, so that it can not be disconnected by mistake.4.

Power on the computer.Continue with next step – Installing the Fingerprint Identification Software.Installing the FingerprintIdentification SoftwareNOTE: Only users with administrator rights can install the software.The fingerprint identification software, Precise 100 Client, is needed to read your finger-prints and to save and retrieve information about your fingerprints, accessible domains,etc.During installation you may be instructed to restart your computer before continuing to thenext step in the installation procedure. If the Master Setup screen does not appear auto-matically after restart, start the CD from your desktop by double-clicking My Computer >CD > MasterSetup.exe icon.NOTE: Once the software is installed, you will be able to register fingerprints using theBioManager (see The BioManager chapter for details) and store them locally if you logon as administrator on your local workstation. However, that will not grant access todomain server accounts. To be able to log into a domain server account using your fin-gerprint, your fingerprint will have to be registered and stored on the domain server.When the fingerprint identification software is installed on your local computer, see adomain administrator to register your fingerprints on the domain server.Chapter 2 InstallationChapter 2 Installation
16Installing the Precise 100 Client SoftwareNOTE: After installation, the computer has to be restarted before you can use the software.1. Log into your local computer as administrator. It is strongly recommended that allWindows programs are closed and no disk is in the disk driver.2. Insert the enclosed Precise 100 Client software CD into your computer’s CD-ROM drive. The Master Setup screen appears.Master Setup screenNOTE: If the CD does not start automatically, start the CD by clicking Start > Run. EnterD:\MasterSetup.exe, where “D” is the name of your CD drive. Click OK.3a. If you have a Precise 100 SC USB reader, connect the fingerprint reader to your computer. Windows 2000 will no detect the new hardware and install the necessary drivers from the CD. 3b. If you have Precise 100 SC PAR reader, click the Parallel Driver button to install the necessary parallel port drivers.4. If you are using Windows NT you must install the updated Microsoft Smart Card Base Components, if not previously installed.

Remove the software CD from the CD-ROM drive before restarting the computer.The software is now saved on your hard drive.5. See a domain administrator to register your fingerprints, if you want to be able to log into a domain server. If you only want to log into your local system, you can register your own fingerprints. You must have administrator rights to register fingerprints. See Fingerprint Registration in chapter 4 for details.Precise DemoIt is recommended that you practice registering and verifying fingerprints for a fewminutes using the Precise Demo. This will help you to practice finger positioning whichwill make it easier to log on using the fingerprint reader. When you are using the Demo,none of your operations will affect your system.Start the Precise Demo by clicking Start > Programs > Precise Biometrics > Demo.Chapter 2 Installation
18Port ConfigurationIf you are using Windows NT (only) and your system is equipped with multiple parallelports, you can specify which parallel port the fingerprint reader is connected to. This isdone in Precise Biometrics Registry Settings. In the rare case you should experience com-patibility problems with other software, you may also need to turn interupts on or off. 1. Click Start > Settings > Control Panel. The Control Panel screen appears. 2. Double-click on the Precise Biometrics logo. The Precise Biometrics Registry Settings screen appears.3. Make the desired changes and click OK.Chapter 2 Installation
19Attaching the Fingerprint ReaderIf preferable, the fingerprint reader can be attached to, for example the side of your mon-itor. Simply use the adhesive tape at the back of the fingerprint reader. The adhesive tapeis very durable and will keep the fingerprint reader attached for many years. The finger-print reader can be removed and attached again. If the adhesive tape loses its stickiness,replace it with one of the enclosed adhesive tapes. Before attaching the fingerprint reader, make sure that it will be comfortable for you touse the fingerprint reader in its new place. Try some different positions to find out which isthe best before removing the adhesive tape cover strip. If you are right-handed, the rightside of your monitor will probably work best, and vice versa.NOTE: If you attach the fingerprint reader to a monitor and want to use it with a smartcard, place the fingerprint reader close to the monitor’s front. In this way, you can easilyinsert and remove the smart card.1. Make sure the surface on which you want to attach the fingerprint reader is perfectly clean.2. Remove the cover strip from the adhesive tape at the back of the fingerprint reader.3. Attach the fingerprint reader by pressing it to the surface. Replacing the Adhesive TapeIf the adhesive tape has lost its stickiness, use the enclosed adhesive tapes. The enclosedadhesive tapes have a cover strip on both sides.1. Remove the old tape from the fingerprint reader before attaching the new adhesive tape.2. Remove one cover strip from the new tape and press the sticky side to the fingerprint reader.3. Finally remove the remaining cover strip and attach the fingerprint reader to the desired surface.Chapter 2 Installation
20Chapter 3As with most new technology, it might take some training to feel at home logging onusing your fingerprint. When you log on and verify your fingerprint, it is important thatyou place your finger on the fingerprint reader in a proper way. The following chaptercontains some examples of good and bad ways of placing your finger on the fingerprintreader.It is highly recommended that you practice by using the Precise Demo for a few minutes(see Precise Demo in the previous chapter for details).This chapter includes the following information:• Placing your finger correctly on the fingerprint reader• Fingerprint reader maintenanceUsing theFingerprintReaderChapter 3 Using the Fingerprint Reader
21Placing Your Finger Correctlyon the Fingerprint ReaderWhen you place your finger on the fingerprint reader sensor to identify yourself, pleaseremember two things: 1. It is important that you use the correct finger. For example, if you place your left index finger on the sensor, you will not be granted access if the system expects you to use your left middle finger. When logging on, a screen shows you which finger you are expected to use – it is marked with a dot. 2. Your finger should be properly positioned on the sensor. Poor positioning and too much or too little pressure could result in an erroneous reading – which may prevent you from gaining access to the system. How to Place Your Finger • Do not “roll” your finger pad. Slide it on to the sensor so that the centre of your finger pad is placed in the sensor centre.• Let the top of your finger pad touch the two dots on top of the fingerprint reader while pressing the finger pad to the sensor.• Use medium pressure and avoid rotating your finger. Keep it still when on sensor.The following graphics show some examples of different fingerprint images:Chapter 3 Using the Fingerprint Reader
22Rotated fingerPoor image:rotated fingerprint.Skew finger – too far to the right.Poor image:off-centre fingerprint.Chapter 3 Using the Fingerprint Reader
23Finger placed too far down on the sensorPoor image:off-centre fingerprint.Perfectly placed fingerGood image:fingerprint in the middle, medium pressure to the sensor.Chapter 3 Using the Fingerprint Reader
24When you are placing your finger on the fingerprint reader sensor, it is important that youuse the finger marked in the Verify Fingerprint window.Above is a good fingerprint, which will result in a perfect match and system access.If the placement is correct, but too much or too little pressure is used, the images will looklike this:Poor image:too dark fingerprint caused by exces-sive pressure. The finger may also bewet.Good image fromthe sensorPoor image:faint fingerprint caused by insufficientpressure. The finger may also be verydry.Chapter 3 Using the Fingerprint ReaderChapter 3 Using the Fingerprint Reader
25Above is a good fingerprint, which will not result in a match since the fingerprint is notmatched with its corresponding template. You may have placed the wrong finger on thesensor, or it could be an unauthorised person trying to log into your account. The systemwill deny access.To learn more about how to position your finger on the fingerprint reader, use the PreciseDemo. To start the Precise Demo, click Start > Programs > Precise Biometrics > Demo.High electrostatic discharges might damage the fingerprint sensor. If your Precise 100Reader is used in an environment where there is a high risk of electrostatic dischargeswhen putting the finger on the sensor, it is important to follow the instructions below. Werecommended to always use the Precise 100 Reader as described here. When puttingthe finger on the sensor, let your finger slide via the finger guide towards the sensor (seepicture).When putting the finger on the sensor multiple times in a short time period, e.g. duringenrolment, you only have to slide via the finger guide the first time you put your finger onthe sensor.Good image fromthe sensorTemplate storedin databaseChapter 3 Using the Fingerprint Reader
26Fingerprint Reader MaintenanceIt is very important that the sensor surface is kept clean. If the sensor is dirty or scratched, there is an increased risk that a fingerprint can not be successfully matchedwith its corresponding template stored in the database. • Protect the fingerprint reader from any kind of physical damage.• If necessary, clean the surface with a clean cotton cloth. You can dampen the cloth slightly with a cleaner.• Do not use paper tissue for cleaning purposes, since it may scratch the surface.• Do not spray cleaner directly onto the fingerprint reader.Chapter 3 Using the Fingerprint ReaderChapter 3 Using the Fingerprint Reader
27Chapter 4The BioManager is the heart of the fingerprint identification system. This chapter address-es the process of enrolling a user into the fingerprint database system and registering auser’s fingerprint data.NOTE: Chapter 4 is for administrators. Users without administrator rights do not haveaccess to the BioManager.This chapter includes the following information:• The BioManager• Primary logon fingers• Passwords• Security level • Registering fingerprints• Adding a new user• Enrolling an existing user• Checking and changing a user’s properties• Deleting a userTheBioManagerChapter 4 The BioManager
28Introduction to theBioManager In the BioManager, information about users, fingerprints, preferences and accessibledomains is stored. Administrators can:• Add and delete users• Register fingerprints• Turn password users into biometric users • Decide whether a biometric user is allowed to use a password as backup• Change properties for users • Set the security level for the systemUsers are listed in the BioManager with a symbol next to each username. The following symbols are used to define a user’s current status:Fingerprint user, with fingerprint information stored on the hard drive. Smart card user. User with fingerprint information stored on smart card.Password user. Can not log on using a fingerprint yet, must use a passwordNOTE: If a password user is enrolled into the fingerprint database system, the currentpassword will no longer be valid.Accessing the BioManagerClick Start > Programs > Precise Biometrics > BioManager. The BioManager screenappears. Chapter 4 The BioManager
29About Primary Logon FingersThe primary logon finger is the finger normally used to log on. The system assumes thatthe selected primary logon finger is placed on the fingerprint reader when a user logsinto or unlocks a workstation. The fingerprint on the sensor is then compared to theprimary logon fingerprint template in the database. The user can not change primarylogon finger, but he or she can easily choose to verify another registered finger whenlogging on. The primary logon finger is chosen during enrolment, in the Fingerprint registrationwizard. The wizard is accessed by clicking User > New User or User > Properties at theBioManager screen. Any registered finger can be chosen as primary logon finger. Tochange Primary Logon Finger, see Checking and Changing a User’s Properties at the endof this chapter. When the fingerprint registration has been completed, please notify the enrolled userabout the primary logon finger. About PasswordsIt is possible to let a fingerprint user log on with a backup password, if this option is cho-sen during enrolment. It is not recommended, however, as passwords make it easier foran unauthorised person to log into the user’s account. NOTE: Only use the password option if the user really needs an alternative to fingerprintsfor logon. If the user uses a laptop computer at work and uses the same laptop at home or whentravelling, a password could be very useful. At logon, the user can choose to log onusing a fingerprint reader or by writing a password. NOTE: If the password logon possibility is not chosen, the user can only log on using afingerprint. If a current password user is enrolled into the fingerprint database system, thecurrent password will no longer be valid.Chapter 4 The BioManager
30About the Security LevelThe security level is an important part of the identification system. A higher security levelreduces the risk of an unauthorised person logging into an account. An administrator canset the security level for biometric users. The security level is set globally; i.e. the set secu-rity level affects all biometric users in the domain. The False Acceptance Rate, FAR, is a parameter used to indicate the probability that anunauthorised user is given access to an account. The False Rejection Rate, FRR, indicatesthe probability that an authorised user is denied access to an account.A secure system, i.e. a system with a high security level, means a low false acceptance rate. • Higher security levels = an excellent match between the fingerprint on the sensor and the fingerprint template in the database is required. The FAR is very low; the FRR is comparatively high.• Lower security levels = a less perfect match between the fingerprint on the sensor and the equivalent fingerprint template in the database is required. The FAR is comparatively high; the FRR is low.Higher security levels (level 6 or 7) result in:• A very secure system. It will be virtually impossible for an unauthorised person to log into a user account. • A system, which sometimes rejects an authorised user trying to log into an account. A small scratch, a distorted fingerprint or poor finger positioning on the fingerprint reader may produce a fingerprint that the system does not accept as a satisfactory match to the fingerprint template stored in the database.Lower security levels (level 1or 2) result in:• A less secure system. At lower security levels, the risk of an unauthorised user logging into an account increases. • A system, which very rarely rejects an authorised user who wants to log into an account. Chapter 4 The BioManager
31Security level 4 is recommended to guarantee a reliable system that grants easy accessto authorised users while barring unauthorised users.When should the higher and lower levels be selected? A lower security level is selectedwhen there is little risk of an unauthorised user attempting to log on, and a very fast verification process is desirable. A higher security level is selected when secu-rity is the main concern. In this case, the verification process may take a little longer.NOTE: An experienced biometric user is less likely to be falsely rejected than a novicebiometric user. The FRR decreases as a user gets more used to biometric logon and learnsa proper finger placement.Setting the Security LevelThe security level is accessed from the BioManager.1. Click Start > Programs > Precise Biometrics > BioManager. The BioManager screen appears. 2. Click Security > Security Level. The Security Level screen appears. Set the security level and click OK. Security level 4 is recommended for most purposes.Chapter 4 The BioManager
32Passwords and Security LevelIf an administrator allows users to log on with a password, a high security level loses partof its function. Even if the system is very restrictive when fingerprints are verified, the securitymight suffer from users who write down passwords on notepads or choose a very simplepassword, which can easily be cracked. Fingerprint RegistrationIn order for a user to use a fingerprint to log on, the fingerprint must be read and stored ina database – i.e. it has to be registered. The fingerprint data will be stored on a harddrive.Only an administrator can register fingerprints using the BioManager.

50Chapter 7Fingerprint TroubleshootingIf the fingerprint verification fails, the red light on the fingerprint reader is turned on. • Lift your finger and put it back on the sensor. Try to slightly adjust the positioning of your finger.• Make sure you placed the right finger on the sensor, i.e. the finger marked with a dot on the Verify Fingerprint screen.• Try to log on using another registered fingerprint.• Place your finger flat on the sensor – not rotated in any direction. See Placing Your Finger Correctly on the Fingerprint Reader in the Using the Fingerprint Reader chapter for more information.• Place the centre of your finger pad in the sensor centre.• Apply enough pressure – the fingerprint reader must be able to detect the fingerprint contours.• Your finger must not be wet. • If your finger pad is too dry try breathing on your finger before verification.• The sensor must be clean. If necessary, gently wipe the sensor with a soft cotton cloth dampened with a mild ammonia-based cleaner.• If using the parallel port, the parallel port must be set to ECP mode. See Setting the Parallel Port in the Installation chapter for more information.• Check that the computer and fingerprint readers are properly connected. See Connecting the Fingerprint Reader in the Installation chapter for more information.If you are still unable to log on, please contact an administrator:• You might need to register your troublesome fingerprint one more time, or register a new fingerprint. • Your user account might be deleted.TroubleshootingChapter 7 Troubleshooting
51Smart Card TroubleshootingIf your smart card can not be read, remove it from the fingerprint reader.• Insert the smart card with the chip end first and the chip facing upwards.• Make sure the chip is not dirty. You can clean it by gently rubbing a softcotton cloth over the chip surface.• If you are using the parallel port, it must be set for ECP mode. See Setting the Parallel Port in the Installation chapter for more information.• Check that the computer and fingerprint reader are properly connected.

54GlossaryBiometricA biometric is a measurable, unique, physical characteristic. For example, the pattern onyour retinas and your fingerprints are biometrics. ECP/Enhanced Capabilities PortThe Precise 100 A PAR and Precise 100 SC PAR readers communicates with the comput-er via the computer’s parallel port. To make the fingerprint reader and computer communi-cate properly via the parallel port, the parallel port must be set to a mode called ECP –Enhanced Capabilities Port. Most new computers are set to ECP by default, but not all.See the Installation chapter for details. This does apply for USB readers.EnrolmentThe process of registering your fingerprints is sometimes referred to as enrolment, as youare enrolled into the system as a biometric user. See Registration for more details. Finger PadThe finger pad is the part of your finger containing the fingerprint. If you take a closerlook on your finger pad, you will find that most of the information in the fingerprint comesfrom the middle of the finger pad. That is the part, which should be placed in the middleof the sensor when you register or log on.Fingerprint ReaderThe fingerprint reader is used for two things: to read a finger placed on the sensor, and toread and store information on a smart card. The sensor measures the capacitance of thefinger pad, which reveals the pattern of the fingerprint. Thus, a paper copy with a pictureof a fingerprint can not grant access to the system.The fingerprint reader is used both to enrol a fingerprint to store it in a database, and toverify a fingerprint during logon. If you have a personal smart card, insert it into the slotbefore placing your finger pad on the sensor.Guiding bumpsDiodesmart card slot
55Fingerprint registrationSee RegistrationFingerprintsYour fingerprint can be described as a pattern of lines or ridges with valleys in between.The lines form specific patterns that are observable to the naked eye. Loops, arches andwhirls are examples of patterns found in a fingerprint.Some finger print structuresThe fingerprints also include so-called minutiae points. Minutiae points are the points,where a ridge begins, ends or splits. Precise Biometrics’ system identifies a person bylooking at loops, arches, whirls and minutiae points, and by measuring global featuressuch as line thickness and curve. These features make every fingerprint unique. Plug-n-playPlug and Play is a technology that supports automatic configuration of PC hardware andexternal devices. A user can just attach a new device such as sound card or peripheraldevices (”plug it in”) and start working (”begin playing”) without having to configure thedevice manually. Plug and Play technology is implemented in hardware, in operating sys-tems, and in supporting software such as drivers and BIOS.Primary logon finger The primary logon finger is the finger normally used when logging into the system. Thesystem assumes that you place your selected primary logon finger on the fingerprintreader when you log on or unlock a workstation. The fingerprint on the sensor is thencompared to the primary logon fingerprint template in the database. For example, if yourright index finger has been selected as the primary logon finger, the right index finger ismarked on the Verify Fingerprint screen, which appears when you log on or unlock aworkstation.

56RegistrationWhen an administrator enrols you into the fingerprint database system, your fingerprintswill be registered. You will have to place each finger pad on the fingerprint reader sensorfour times. The best image will be saved in a database. Registered fingerprints are usedwhen you log into the system. For example, if your right index finger has been registered,you can place your right finger on the fingerprint reader sensor to verify your identitywhen you log on. The fingerprint on the sensor will be compared to the registered finger-print. If your fingerprint on the sensor matches the fingerprint in the database, you aregranted access to the system.NOTE: Once the software is installed, you will be able to register fingerprints using theBioManager (see The BioManager chapter for details) and store them locally if you logon as administrator on your local workstation. However, that will not grant access todomain server accounts. To be able to log into a domain server account using your fin-gerprint, your fingerprint will have to be registered and stored on the domain server.Sensor The sensor is the black window on the fingerprint reader. The sensor is used to read yourfingerprint. Do not “roll” your finger pad when you log on or register a fingerprint. Justpress it flat to the sensor.Smart CardA smart card is a card with information stored in a small chip. The smart card can bedescribed as some kind of miniature computer – it has a small processor and memory.The difference is that the smart card is passive, i.e. it has no internalpower supply, and must hence rely on power from some kind of equip-ment. When the smart card is inserted into the fingerprint reader, it “awak-ens”. The fingerprint reader supplies the necessary power, and the com-puter reads information from the chip. It is thus important to keep the chipclean. If the chip looks dirty, you can clean it carefully with a soft cottoncloth.Smart Card Base ComponentsSmart Card Base Components provide the necessary files needed to enable applicationsto communicate with a smart card through a reader attached to a PC.Verification When you register a fingerprint, log on or unlock a system, your fingerprint is verified.During verification, the finger on the sensor is compared to a template of a registered fin-gerprint from the fingerprint database. In other words, you verify that you indeed are whoyou claim you are and that the fingerprint on the sensor matches the fingerprint templatein the database.
