9.7.3 Access conditions for data blocks
Depending on the access bits for data blocks (blocks 0...2) the read/write access is
specified as ‘never’, ‘key A’, ‘key B’ or ‘key A|B’ (key A or key B). The setting of the
relevant access bits defines the application and the corresponding applicable commands.

Read/write block: The operations read and write are allowed.
Value block: Allows the additional value operations increment, decrement, transfer
and restore. In one case (‘001’) only read and decrement are possible for a
non-rechargeable card. In the other case (‘110’) recharging is possible by using key B.
Manufacturer block: The read-only condition is not affected by the access bits setting!
Key management: In transport configuration key A must be used for authentication
if Key B may be read in the corresponding Sector Trailer it cannot serve for authentication (all grey marked
lines in previous table). Consequences: If the reader tries to authenticate any block of a sector with key B
using grey marked access conditions, the card will refuse any subsequent memory access after
authentication.
