3.0. Smart Card Support
3.1. MCU Cards
ACR3901U-S1 is a PC/SC-compliant smart card reader that supports ISO 7816 Class A, B, and C (5
V, 3 V, and 1.8 V) smart cards. It also works with MCU cards following either the T=0 and T=1
protocol.
The card ATR indicates the specific operation mode (TA2 present; bit 5 of TA2 must be 0) and when
that particular mode is not supported by the ACR3901U-S1, it will reset the card to negotiable mode. If
the card cannot be set to negotiable mode, the reader will then reject the card.
When the card ATR indicates the negotiable mode (TA2 not present) and communication parameters
other than the default parameters, the ACR3901U-S1 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 ISO 7816-3.
3.2. Memory-based Smart Cards
