MIFARE Classic 4K - Mainstream contactless smart card IC
8.7.2
Access conditions for the sector trailer
Depending on the access bits for the sector trailer (block 3, respectively block 15) 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 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.
Table 7.
