MIFARE Classic 4K - Mainstream contactless smart card IC
8.7 Memory access
Before any memory operation can be carried out, the card has to be selected and
authenticated as described in
Section 8.2
. The possible memory operations for an
addressed block depend on the key used and the access conditions stored in the
associated sector trailer.
Table 4.

8.7.1
Access conditions
The access conditions for every data block and sector trailer are defined by 3 bits, which
are stored non-inverted and inverted in the sector trailer of the specified sector. For the
upper 8 sectors, always 5 blocks share the same access rights (see
Table 5
).
The access bits control the rights of memory access using the secret keys A and B. The
access conditions may be altered, provided one knows the relevant key and the current
access condition allows this operation.
Remark:
With each memory access the internal logic verifies the format of the access
conditions. If it detects a format violation the whole sector is irreversibly blocked.
Remark:
In the following description the access bits are mentioned in the non-inverted
mode only.
The internal logic of the MF1S703x ensures that the commands are executed only after a
successful authentication.
