8.7.2 Access conditions for the sector trailer
Depending on the access bits for the sector trailer (block 3) the read/write access to the

key B).
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 the transport configuration, new cards
must be authenticated with key A. Since the access bits themselves can also be blocked,
special care has to be taken during the personalization of cards.
