Supported card types
The ACR38 can operate MCU cards with T=0 and T=1 protocol in its main card slot.
Microcontroller-based smart cards (asynchronous interface)
The ACR38 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 ACR38 performs the Protocol and Parameters Selection (PPS) procedure as specified in ISO7816-3:
1997.
When the card ATR indicates the specific operation mode (TA
particular mode is not supported by the ACR38, 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
than the default parameters, the ACR38 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.
