MIFARE Classic 1K - Mainstream contactless smart card IC
8.7.3
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. With access condition ‘001’ only read and decrement are possible which
reflects a non-rechargeable card. For access condition ‘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
Table 8.

If key B may be read in the corresponding Sector Trailer it cannot serve for authentication (see grey marked
lines in
Table 7
). As a consequences, if the reader authenticates any block of a sector which uses such
access conditions for the Sector Trailer and using key B, the card will refuse any subsequent memory
access after authentication.
