Example 1:
ATR for DESFire = { 3B 81 80 01 80 80h } // 6 bytes of ATR
Note: Use the APDU “FF CA 01 00 00h” to distinguish the ISO 14443A-4 and ISO 14443B-4 PICCs,
and retrieve the full ATS if available. ISO 14443A-3 or ISO 14443B-3/4 PICCs do have ATS returned.
APDU Command = FF CA 01 00 00h
APDU Response = 06 75 77 81 02 80 90 00h
ATS = {
06 75 77 81 02 80h }
Example 2:
ATR for EZ-Link = {3B 88 80 01
1C 2D 94 11 F7 71 85 00 BEh}
Application Data of ATQB = 1C 2D 94 11h
Protocol Information of ATQB = F7 71 85h
MBLI of ATTRIB = 00h
