Remark:
The minimum required time between MIFARE Write part 1 and part 2 is the
minimum required FDT acc. to
Ref. 4
. There is no maximum specified.
11.4 MIFARE Increment, Decrement and Restore
The MIFARE Increment requires a source block address and an operand. It adds the
operand to the value of the addressed block, and stores the result in a volatile memory.
The MIFARE Decrement requires a source block address and an operand. It subtracts the
operand from the value of the addressed block, and stores the result in a volatile memory.
The MIFARE Restore requires a source block address. It copies the value of the
addressed block into a volatile memory.
These two parts of each command are shown in
Figure 17
,
Figure 18

Table 18
.
Table 19
