9.7.2 Access conditions for the sector trailer
9.7.3 Access conditions for data blocks
Depending on the access bits for the sector trailer (block 3) the read/write access to the
keys and the access bits is specified as ‘never’, ‘key A’, ‘key B’ or key A|B’ (key A or
key B).
On chip delivery the access conditions for the sector trailers and key A are predefined as
transport configuration. Since key B may be read in transport configuration, new cards
must be authenticated with key A. Since the access bits themselves can also be blocked,
special care should be taken during personalization of cards.
Table 6.

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.

for this access condition key B is readable and may be used for data
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
