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.
