3.5.1. Contact Smart Card Reader

The contact smart card reader is an 8-pin, ISO7816 compliant contact smart card reader for ID-
000 smartcards. Its contacts C4 and C8 are connected with the internal RF antenna. Thus it is
possible to use beside normal smartcards (microprocessor and memory cards) also dual interface
smartcards with additional contacts on C4 / C8. Memory cards can be accessed using SCM's
Memory Card DLL.
Note: Memory cards which supports C4 /C8 will not be able to work as these pins are used for the
RF antenna.
Within a Windows® environment the smart card reader can be used with the PC/SC driver or with a
preinstalled USB-CCID driver.
Windows® Vista and future Windows® operation systems have the USB-CCID driver as standard
driver already installed. If Windows® XP is used as operating system, the USB-CCID driver is
available as optional update.

Use
Power connection through which operating power is supplied
to the microprocessor chip in the card
Reset line through which the IFD can signal to the smart
card's microprocessor chip to initiate its reset sequence of
instructions
Clock signal line through which a clock signal can be provided
to the microprocessor chip. This line controls the operation
speed and provides a common framework for data
communication between the IFD and the ICC
RF antenna
Ground line providing common electrical ground between the
IFD and the ICC
Programming power connection used to program EEPROM of
first generation ICCs.
Input/output line that provides a half-duplex communication
channel between the reader and the smart card
RF antenna
