9.19 Property 0x56 - MagnePrint Data Encryption Variant (MSR Only,
Configurable MagnePrint Variants Only)
Property ID: 0x56
Property Type: Byte
Length: 1 byte
Get Property: Yes
Set Property: Yes
Default Value: 0x00 (PIN Variant)
This property specifies which variant of the current DUKPT Key the device uses to encrypt magnetic
stripe Encrypted MagnePrint Data:
 0x00 = Use PIN Encryption variant
 0x01 = Use Data Encryption, request or both ways variant
The host software should use this value to determine how to create the correct Derived Key to decrypt
Encrypted MagnePrint Data (see section 5 Encryption, Decryption, and Key Management). The
algorithms for creating the Derived Key fitting each of the possible variants are fully specified in ANS
X9.24-1:2009.
Some devices are configured to only allow the manufacturer to modify this property.
This property is stored in non-volatile memory, so it persists when the device is power cycled. When this
property is changed, the device must be reset (see Command 0x02 - Reset Device) or powered off for at
least 30 seconds, then powered on, before the changes will take effect.
