7.3 MIFARE authenticate block (key A or key B)
Use this command to authenticate the specified MIFARE block against the MIFARE media’s internal
Key A or B.
You must load the MIFARE key using MIFARE load key (on page 40) before sending this command.
The MIFARE authenticate block command is largely used for test purposes. The other MIFARE
commands use this command internally to check that the key is loaded and responds. It checks
whether the MIFARE keys are correctly loaded.
Note: This command is NOT applicable to MIFARE Ultralight cards and fails if executed on
Ultralight cards. Ultralight cards do not support the authenticate command.
