Setting up contactless reader parameters (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:
Blocks are numbered in an absolute way, 1 for block 0 sector 0,
then 3 blocks for each sector.
SAGEM SA 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.
For more information about SAGEM SA biometric data, please
contact SAGEM SA or refer to document 3000005996
MorphoAccess™ Host System Interface Specification.
With a MorphoAccess™ 220, contactless parameters can be
