Mainstream contactless smart card IC
Remark: The minimum required time between MIFARE Increment, Decrement, and
Restore part 1 and part 2 is the minimum required FDT acc. too Ref. 4
. There is no
maximum specified.
Remark: The MIFARE Increment, Decrement, and Restore commands require a MIFARE
Transfer to store the value into a destination block.
Remark: The MIFARE Increment, Decrement, and Restore command part 2 does not
provide an acknowledgement, so the regular time out has to be used instead.
11.5 MIFARE Transfer
The MIFARE Transfer requires a destination block address, and writes the value stored in
the volatile memory into one MIFARE Classic block. The command structure is shown in
Figure 19
and Table 20.
Table 21
shows the required timing.
Table 19. MIFARE Increment, Decrement and Restore timing
These times exclude the end of communication of the PCD.
