9.3 MIFARE Classic ACK and NAK
9.4 ATQA and SAK responses
Remark: Due to the coding of commands, the measured timings usually exclude (a part
of) the end of communication. This needs to be considered, when comparing the specified
with the measured times.
The MIFARE Classic uses a 4 bit ACK/NAK as shown in
Table 9.
For details on the type identification procedure please refer to
The MF1S503x answers to a REQA or WUPA command with the ATQA value shown in
Table 10
