SCL3711 REFERENCE M ANUAL 12 3.5. Contactless communication principles and SCL3711 usage recommendations 1 SCL3711 is a contactless reader designed to communicate with user tokens. User tokens 2 User tokens are made of a contactless integrated circuit card connected to an antenna Credit card sized smart card • Key fob • NFC mobile phone etc… 1 71 L3 • SC User tokens can take several form factors: Communication between SCL3711 and user tokens uses magnetic field inductive coupling.
SCL3711 REFERENCE M ANUAL 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.
SCL3711 REFERENCE M ANUAL 3.6. 14 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.
SCL3711 REFERENCE M ANUAL 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.

SCL3711 REFERENCE M ANUAL 20 5.3.3. PC/SC 2.0 compliant ATR 5.3.3.1. Determining the technology of the user credential The ScardControl method of PC/SC (see http://msdn.microsoft.com/enus/library/aa379474(VS.85).aspx) should be used to send the 0x90 IOCTL to SCL3711 in order to determine what type of technology is the user token based on.
SCL3711 REFERENCE M ANUAL 5.3.3.2. 21 ATR for type A memory user tokens The ATR of the user token is composed as described in the table below. In order to allow the application to identify the storage card properly, it’s Standard and Card name describing bytes must be interpreted according to the Part 3 Supplemental Document, maintained by PC/SC.

SCL3711 REFERENCE M ANUAL 5.3.3.4. 23 ATR for a NFC Forum tag type 3 user token (FeliCa) Byte# Value Designation Description 0 0x3B Initial header 1 0x8C T0 TD1 present.
SCL3711 REFERENCE M ANUAL 5.3.3.5. 24 ATR for ISO/IEC 14443-4 user tokens The user token exposes its ATS or application information which is mapped to an ATR. The table describes how this mapping is done. Byte# Value Designation Description 0 0x3B Initial header 1 0x8n T0 n indicates the number of historical bytes in following ATR 2 0x80 TD1 Nibble8 indicates no TA2, TB2, TC2 Nibble 0 means T=0 3 0x01 TD2 Nibble8 indicates no TA3, TB3, TC3 Nibble 1 means T=1 4...
SCL3711 REFERENCE M ANUAL 5.4. 25 Firmware 5.4.1. Transport protocol SCL3711 implements a transport protocol which is proprietary to NXP Semiconductors. 5.4.2. Automatic PPS Automatic PPS implemented is implemented. SCL3711 will automatically switch the highest baud rate commonly supported by the SCL3711 and the user token The maximum speed supported by SCL3711 is 848Kbps by default.
