8.4.3.20 Write master key
This command stores a mifare
®
Standard key into the master key memory of the
reader. The reader can store up to 32 keys.
Command
Command Data
'wm' Key number (1 byte) 00h … 1Fh
Key (6 bytes)
Answer
Answer Description
data Written key (6 bytes)
'F' Error: Write failure
'R' Error: Out of range
Example
Command Description
wm00112233445566 Store key 112233445566h in EEPROM (key
number 0).
wm02A0A1A2A3A4A5 Store transport key 1 in EEPROM key 2.
8.4.3.20.1 Out of range failure 'R'
The entered key index exceeds the address range.
8.4.3.20.2 Writing master keys
Keys are Write-Only. It is not possible to read the keys. Nevertheless the reader
returns correct error messages if the writing process fails.
A verification of the master key can only be done using an appropriate card and
following successful login.
8.4.3.20.3 Using master keys for authentication
Master keys may be used for ISO-14443 A tag authentication. It is possible to use
every stored key for key A as well as key B authentication.
Each key is 6 bytes long and stored redundantly for data security.
