Table 20 - Access Condition for Data Blocks
The MIFARE
®
system regards authentication Key B as the primary key for access control to
the data memory. Operations which are performed with authentication Key A can also be
done with authentication Key B. But, only some sensitive operations can be performed with
Key B.
The previous Table “Access Bits and the Valid Commands” shows the types of access
conditions associated with their bit values and the access granted by authentication with
Key A and Key B.
