ISO/IEC 14443 compliant means not neccessaryly compliant to ISO/IEC
14443-4. The GCA680 is a MIFARE reader. MIFARE uses ISO/IEC 14443-3 type
A anticollision, but on the higher level it does its own protocol. So
the MIFARE cards do not speak T=CL and the command format is not that
of APDUs. What Gemplus probably did is taking the Philips MIFARE ASIC
and build another IC, which speaks to the host with the TLP proctocol
and translates the APDU formated commands to the ASIC commands.
