10.3 MIFARE ACK and NAK
All timing can be measured according to ISO/IEC 14443-3 frame specification as shown
for the Frame Delay Time in
FDTPCD2PICC = Frame delay time PCD to PICC.
FDTPICC2PCD = Frame delay time PICC to PCD (must be at least 87 μS).
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 given
times with the measured ones.
The MIFARE Classic uses a 4 bit ACK / NAK as shown in
Table 9.
