This is a summary Document. A complete document is
available on the Gemplus Web site. www.gemplus.com
The connection with the host processor is achieved via a serial asynchronous link; the rate can
be selected from a range from 1200 to 115,200 bps.
The software inside the GemCore chip handles a communication protocol with the host system
called the Gemplus Block Protocol (GBP).
A complete set of documentation is available on the Gemplus web site:
http://www.gemplus.com.
A GBP Interface Library Kit can be provided, upon request. It consists of the source code of the
GBP communication layer between the host and GemCore. It is written in the C language. See
the Gemplus developers’ site at www.gemplus.com. Enquiries can also be posted to
cardreader@atmel.com.
