Parameter 2
6-byte key
Sector for key in reader's EEP-
ROM
Uses the temporarily stored key: Dummy value (0-63)
Table 125: MIFARE access rights (parameter 2)
"A" = Authentication with key A, "B" = Authentication with key B
Sector
= 0 to 63
Source and target block
= 0 to 254 (depends on type: 0 to 63 for MIFARE 1K, 0 to 254 for MIFARE 4K; for
"Decrement", "Increment" and "Restore", the source block must be a value block)
Data and key
= 00 to FF (no leading "0x", bytes can optionally be separated by a space)
Value
= 4 bytes including sign bit
All commands and parameters are in ASCII. Data is in 00h hex format.

Table 127: MIFARE access rights - Parameters 2, 3 and 4 (data blocks)
If key B is read in the corresponding sector trailer, it cannot be used for authentication (all of the yellow rows in
the table above).
Consequences:
If the reader attempts to authenticate a block in a sector with key B (access conditions marked
in yellow), the tag will refuse all subsequent memory access following authentication.
