Binary Data
Description
The MorphoAccess® SIGMA Family terminal is able to use a binary value to read on specific
location on user’s card, as user’s identifier. The terminal in legacy modes can also write smart
card in binary data format.
As a sample of binary value, the serial number of the card can be used, as explained in the
“Example: MIFARE® card Serial Number” in this section subsequently.
The MorphoAccess® SIGMA Family terminal is able to read a binary value which is not aligned
on complete bytes. This ability is useful to extract the user’s identifier from a Wiegand frame
written on the user’s card. A sample is described in “Example: 32 bits user’s identifier within a
37-bits Wiegand frame” section.
No TLV structure is required on user’s card: the MorphoAccess® SIGMA Family terminal is able
to proceed with user’s cards written by other systems.
Card type compatibility
This feature can only be used when the “MIFARE® card only” mode is set (User ID in binary or
TLV format). Then the related configuration key must be set to zero.
Type of contactless smartcard enabled
sc.encode_profile = 2
MIFARE® card only (identifier of the user is a
binary value).
Configuration keys
The binary data to be read is defined by:
the first block containing the data,
the offset of the first byte and first bit of the data, inside the sector. This value must not
exceed 15 bytes. The terminal can read data that doesn’t start on a full byte,
the length in bytes and additional data bits; this must not exceed 8 bytes. The terminal
can read data where the length is not a multiple of 8 bits,
the read direction: MSB or LSB.
