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.
