1 Introduction
The Scheidt & Bachmann (S&B) 13,56 MHz RFID Smart Card Reader System “SCR” is
designed for exclusive application with S&B devices only. It will never be sold as single
system. S&B devices are products like ticket vending machines, pay on foot machines,
ticket dispensers, ticket validators etc. with
13,56 MHz RFID functionality.
SCR is integrated by a set of one common sandwich circuit board and one or two (see cp. 4)
of 2 different antenna types.
For operational description, pls. see cp. 2.
For block diagram, pls. see cp. 3.
For detailed antenna adaptation and pin assignment, pls. see cp. 4.
For detailed pin assignment, pls. see cp. 5.
For FCC/ IC information, pls. see cp. 6.

2 Operational description
2.1 Basic operation principle
SCR is a 13,56Mhz RFID Transponder Read/ Write Unit for use in S&B equipment. It can be
used for various applications in S&B eqt, such as SmartCards, eTicketing, wireless creditcard
processing (EMV), etc. All such devices are under responsibility of S&B.
Corresponding partners for SCR are passive RFID Transponders, based on the ISO 14443 Type
A and B or Mifare standard. The transponders are passive units; the power supply of
transponders is realized via RF link of the SCR module.
SCR serves as an interface between data medium (transponder) and the S&B subsystem:
RF modulation and demodulation
Digital Data generation and detection
Intermediate memory (for processing and commands)
I/F to S&B eqt. (such as Ticket vending machines)
2.2 System Structure
The processor-based SCR solution consists of two PCBs (CPU module and baseboard):
The CPU module contains the CPU together with an FPGA. All necessary interface lines are fed
to two connectors. The CPU Module is plugged into the baseboard.
On the baseboard resides the power supply that converts the input voltage of 8V—12V into 5V
and 3.3V. Alternatively the SCR can be supplied with a 5V power supply. Additionally two
chips are implemented to interface to two independent antennas for transactions with contact less
smartcards. Another chip is used, to interface to four SAM (secure access module) sockets.
Finally there are all connectors, transceivers and other components integrated, that the SCR
needs to communicate to a host (USB 1.1, RS232) and to the customer (antenna, LEDs, buzzer).
The Smart Card Target (that is the area, where the customer shall tag the contact less smart
card) is a separate PCB, designed as antenna, with LED and a buzzer as user interface. The SCR
supports two independent antennas.
Four SAMs (secure access module) sockets are implemented to handle keys and to store
transaction data (depends on application).
The SCR is equipped with a USB compliant interface to perform upload of transactional and
event data and download of firmware versions and operational data.
The SCR can be equipped with a RS232 interface to perform the same data exchange that is
possible with USB.

2.3 RF coupling of SCR and Transponder
Since electromagnetic coupling is used for data transmission between SCR and transponder and
power supply of the transponder the electromagnetic field is the most important attribute. The
following figure shows the run of the electromagnetic field lines with the transponder placed in
the antenna field.
The RF coupling is according to all layers of ISO 14443 Type A and B are supported.
