With MorphoAccess™ 220, a MIFARE can be used to trigger an
authentication. In that case, biometric data are stored in a TLV format (Tag
– Length – Value).
Data on the card is a concatenation of TLV.
T L V
T: 1 byte data identifier.
L: 2 bytes size of the V field. Length is encoded in little endian.
V: value of the data field.
The section Setting up contactless reader parameters describes the data
location (first block read).
