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 37: MIFARE access rights (parameter 2)
"A" = Authentication with key A, "B" = Authentication with key B
Sector
= 0-63
Source or target block = 0-254 (depending on type MIFARE 1K 0-63, MIFARE 4K 0-254,
with decrement, increment, restore, source block must be of type "value block")
Data and key = 00 - FF (no leading "0x", bytes can optionally be separated by a space)
Value
= 4 byte including sign bit
All commands and parameters are in ASCII. Data is in 00h hex format.
Para1 Para2 Para3 Para4 Para5

er)

Table 38: MIFARE access rights (5-byte parameters)
Value RD WR INCR DECREMENT / TRANSFER / RESTORE Comment
0x00 A / B A / B A / B A / B Full access with every key (de-
fault factory setting)
0x01 A / B B - -

0x04 A / B - - A / B Value block
0x05 B - - -
0x06 B B - -
0x07 - - - - No access
Table 39: 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
marked in gray), then the card will refuse all subsequent memory access following the authentication.
