Mainstream contactless smart card IC
All timing can be measured according to ISO/IEC 14443-3 frame specification as shown
for the Frame Delay Time in Figure 11. For more details refer to Ref. 3 and Ref. 4.
FDTPCD2PICC = Frame delay time PCD to PICC.
FDTPICC2PCD = Frame delay time PICC to PCD (must be at least 87 μS).

Fig 11. Frame Delay Time (from PCD to PICC), and T_ACK and T_NAK
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.
10.3 MIFARE ACK and NAK
The MIFARE Classic uses a 4 bit ACK / NAK as shown in Table 9.
