9.6.3 Sector trailer (block 3)
9.7 Memory access
Each sector has a sector trailer containing the
If key B is not needed, the last 6 bytes of block 3 can be used as data bytes.
Byte 9 of the sector trailer is available for user data. For this byte the same access rights
as for byte 6, 7 and 8 apply.
All keys are set to FFFFFFFFFFFF
Before any memory operation can be carried out, the card has to be selected and
authenticated as described previously. The possible memory operations for an addressed
block depend on the key used and the access conditions stored in the associated sector
trailer.
