Remark:
The minimum required time between MIFARE Write part 1 and part 2 is the
minimum required FDT according to
Ref. 4
. There is no maximum time 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.
All three commands are responding with a NAK to the first command part if the addressed
block is not formatted to be a valid value block, see
Section 8.6.2.1
.
The two parts of each command are shown in
Figure 18
and
Figure 19
and
Table 23
.
