MIFARE Classic 1K - 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
for the Frame Delay Time in
. For more details refer to
and
.
The frame delay time from PICC to PCD must be at least 87
μs.
Remark: Due to the coding of commands, the measured timings usually excludes (a part
of) the end of communication. This needs to be considered, when comparing the specified
with the measured times.
