BCD Encoding
Most FIPS-PIV credential readers use 5-bit BCD encoding (4 bit data, 1
bit parity). This is the only type of data encoding that this system
supports.
Note: The STD_75Bit_PIV format does not use BCD, but its encoding
is well known since it is specified by the FIPS-201 Evaluation
Program.
Schneider Electric’s system does not support FIPS-PIV readers
that output less than 75 bits.
LSB
Data can be sent by readers either with most significant bit first (MSB)
or least significant bit first (LSB).
Note: Schneider Electric’s system only supports data being sent out
LSB first.
To reduce the bit counts for some legacy systems that cannot
handle them, some readers use 4-bit LCD (no parity bit). These
4-bit BCD digit readers are not supported.

CyberStation Procedure
After you determine the correct PIVReaderFormat string variable from
the documentation for the FIPS-PIV card/credential reader, perform
the following procedure.
To create a Custom FIPS-PIV card format using CyberStation version
1.82 or higher, perform the following steps:
1. Check that FIPS-PIV credentials are selected by right-clicking the
Continuum symbol in the tool tray area of the Windows task
bar and selecting Allowed Credentials.
If the current value does not include a FIPS-PIV credential, select
one from the drop-down list and select Change.
