ACS AET63 BioTRUSTKey - Manual (Page 4)

2.0. Supported Card Types
The AET63 can operate MCU card with T=0 and T=1 protocol. The table presented in Appendix A
explains which card type selection value must be specified for the various card types supported by the
reader.
2.1. Microcontroller-Based Smart Cards (Asynchronous Interface)
The AET63 supports EEPROM microcontroller-based cards with internal programming voltage (VPP)
generation and the following programming parameters transmitted in the ATR:
PI1 = 0 or 5
I = 25 or 50
The AET63 performs the Protocol and Parameters Selection (PPS) procedure as specified in
ISO7816-3:1997.
When the card ATR indicates the specific operation mode (TA
2
present; bit b5 of TA
2
must be 0) and
that particular mode is not supported by the AET63, the reader will reset the card to set it to
negotiable mode. If the card cannot be set to negotiable mode, the reader will reject the card.
When the card ATR indicates the negotiable mode (TA
2
not present) and communication parameters
other than the default parameters, the AET63 will execute the PPS and try to use the communication
parameters that the card suggested in its ATR. If the card does not accept the PPS, the reader will
use the default parameters (F=372, D=1).
For the meaning of the aforementioned parameters, please refer to ISO7816, part 3.
