5.5 Access rights
There are various options for parameter 2 depending on the configuration.
MIFARE access rights (parameter 2)
Config
Key_CMD
Key_EEPROM
Key_TEMP
Para2
6-byte key
Sector for key in reader's EEP-
ROM
Uses the temporarily stored key: Dummy value (0-63)
Table 8: MIFARE access rights (parameter 2)
"A" = Authentication with key A, "B" = Authentication with key B
Sector = 0-63
Source and target block = 0-254 (depends on type: 0-63 for MIFARE 1K, 0-254 for MIFARE 4K;
for "Decrement", "Increment" and "Restore", the source block must be a value block)
Data and key = 00- 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 10: 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: When the reader attempts to authenticate a block in a sector with Key B (access conditions
Consequences: When the reader attempts to authenticate a block in a sector with Key B (access conditions
marked in gray), then the card will refuse all subsequent memory access following the authentication.
