SCL3711 REFERENCE MANUAL 10 3. General information about SCL3711 3.1. SCL3711 key benefits With its functional solid mechanical design that has no removable parts that you may loose, SCL3711 is perfect for mobile uses. While being slim, SCL3711 dimensions have been optimized to ensure best RF performance possible with such a form factor. The state of the art multi-protocol feature set of SCL3711 qualifies it to be used in a wide range of applications such as payment, loyalty and ID schemes, or to enable devices with NFC connectivity. As a latest generation product, SCL3711 can be supported by SCM’s middleware that resides above the PC/SC API and offers better portability of applications and abstraction of smart card related details that need to be handled by applications developed on top of the PC/SC API. 3.2.

SCL3711 REFERENCE MANUAL 12 3.5. Contactless communication principles and SCL3711 usage recommendations SCL3711 is a contactless reader1 designed to communicate with user tokens. User tokens2 are made of a contactless integrated circuit card connected to an antenna User tokens can take several form factors: • Credit card sized smart card • Key fob • NFC mobile phone etc… Communication between SCL3711 and user tokens uses magnetic field inductive coupling. The magnetic field generated by SCL3711 has a carrier frequency of 13.56MHz. 3.5.1. Power supply When the user token is put in the magnetic field of the reader, its antenna couples with the reader and an induction current appears in the antenna thus providing power to the integrated circuit. The generated current is proportional to the magnetic flux going through the antenna of the user token. 3.5.2. Data exchange The carrier frequency of the magnetic field is used as a fundamental clock signal for the communication between the reader and the card. It is also use as a fundamental clock input for the integrated circuit microprocessor to function. To send data to the user token the reader modulates the amplitude of the field. There are several amplitude modulation and data encoding rules defined in ISO/IEC 14443 and ISO/IEC 18092. The reader should refer to those standards for further details. To answer to the reader, the integrated circuit card of the user token modulates its way of loading (impedance) the field generated by the reader. Here also further details can be found in ISO/IEC 14443 and ISO/IEC 18092. 1 In the ISO/IEC 14443 standard, the reader is called the proximity coupling device (PCD) 2 In the ISO/IEC 14443 standard, the user token is called proximity integrated chip card (PICC) User tokensSCL3711
SCL3711 REFERENCE MANUAL 13 3.5.3. Recommendations The communication between the reader and the user token is sensitive to the presence of material or objects interfering with the magnetic field generated by the reader. The presence of conductive materials like metal in the vicinity of the reader and the user token can severally degrade the communication and even make it impossible. The magnetic field of the reader generates Eddy or Foucault’s currents in the conductive materials; the field is literally absorbed by that kind of material.  It is recommended for proper communication to avoid putting SCL3711 in close proximity of conductive materials. The presence of multiple user tokens in the field also interferes with the communication. When several user tokens are in the field of the reader, load of the field increases which implies that less energy is available for each of them and that the system is detuned. For this reason, SCM Microsystems has implemented in its driver the support for 1 slot only.  It is recommended to present only one user credential at a time in front of SCL3711. The communication between the reader and the user token is sensitive to the geometry of the system {reader, user token}. Parameters like the geometry and specially the relative size of the reader and user token antennas directly influence the inductive coupling and therefore the communication. SCL3711 was primarily designed and optimized to function with user credentials of various technologies having the size of a credit card.  It may happen that SCL3711 is not capable of communicating with extremely large or extremely small antennas.  In order to optimize the coupling between the reader and the user token, it is recommended to put both antennas as parallel as possible  In order to optimize transaction speed between the reader and the card it is recommended to place the user token as close as possible to the reader. This will increase the amount of energy supplied to the user credential which will then be able to use its microprocessor at higher speeds
SCL3711 REFERENCE MANUAL 14 3.6. Applications 3.6.1. General SCL3711 is a transparent reader designed to interface a personal computer host supporting PC/SC interface with 13.56MHz user tokens like public transport cards, contactless banking cards, NFC forum tags, electronic identification documents – e.g. e-passports, e-ID cards, driving licenses etc. Those user tokens can have several form factors like credit cards, key fobs, NFC mobile phones or USB dongles like SCT3511 that SCM Microsystems markets. SCL3711 itself handles the communication protocol but not the application related to the token. The application-specific logic has to be implemented by software developers on the host. 3.6.2. Applications provided by SCM Microsystems SCM Microsystems does not provide payment or transport applications. SCM Microsystems provides a few applications for development and evaluation purposes that can function with SCL3711. They are available within the software development kit. There are many tools provided but the two main ones are: • The NFC forum tag reader/writer is a standalone application that enables the user to read and write NFC forum compliant records into NFC forum compatible tags. It is an easy to use tool to configure rapidly NFC forum tag demonstrations. • Smart card commander version 1.1 provides a module which for NFC forum tags that parses and presents in XML format the content of the tag. Smart card commander also contains powerful scripting functionality which can be very useful for developers to develop and debug their applications.
SCL3711 REFERENCE MANUAL 15 4. SCL3711 characteristics 4.1. SCL3711 high level architecture 4.1.1. Block diagram The link between SCL3711 and the host to which it is connected is the USB interface providing both the power and the communication channel. SCL3711 is based designed around an NFC controller which handles the USB communication to the host and the RF communication. This controller ensures the coding/decoding/framing modulation/demodulation required for the RF communication. The matching circuitry provides the transmission and receiver paths adaptation for the antenna to function properly. 4.1.2. Software architecture Applications can interface with the driver directly through the PC/SC interface or through the SCM proprietary interface to the NFC wrapper. The NFC wrapper simplifies the usage of the different NFC Forum tags with the SCL3711 and other SCM contactless readers. It provides a unique API to application developers, which enables them to read and modify NDEF records without further knowledge of the underlying hardware and protocols. Detailed information about the NFC wrapper can be found in SCM’s Contactless SDK. The SCL3711 driver implements PC/SC v2.0 API towards upper layers.
