(MorphoAccess™ 220 only)
A MIFARE card is defined by a unique serial number.
• The card is divided in 16 sectors.
• Each sector is divided in 4 blocks.
• Each block contains 16 bytes of data.
• Data are encoded with two sets of key.
To be able to read a card, the reader should use the same key set. Fourth
blocks cannot be read, they are used to store key sets.
Data can be accessed by blocks as follows:
Block 0 Block 1 Block 2
Block 3
Secteur 0
Block 1 Block 2 Block 3
Sector 1
Block 4 Block 5 Block 6
...
Sector 15
Block 46 Block 47 Bloc 48
Blocks are numbered in an absolute way, 1 for block 0 sector 0, then 3
blocks for each sector.
SAGEM biometric data (ID, name and templates) are located on the card
thanks to a BNC address where:
• <B> is the first block number to read,
• <N> is the number of blocks to read,
• <C> selects a security key.
Data are described in Contactless card data structure (MorphoAccess 220
only) section and in document MorphoAccess™ Host System Interface
Specification.
