dwFeature defines Extended APDU for the contactless interface.
Full Extended APDU command length is supported (7+65535+2 = 65544 bytes).
The Extended APDU command must be split into several PC_to_RDR_XfrBlock messages
according to the CCID specification (the PC_toRDR_XfrBlock message length is limited to
dwCCIDMessageLength).
For a Mifare cards the data must be a Short APDU command as defined in PC/SC
specification.
For ISO14443-4 cards the data are send “as it” using the T=CL protocol.
For other proprietary APDU commands, the data must be a Short APDU command.

expired

4 to 502 Data block sent to the CCID.
For a T=CL card this data are send
“as it” using the T=CL protocol.
For a Mifare card: the data must be
a Short APDU command as
defined in PC/SC specification.
The command message length = 10 + Card command length.
