Track 2 Encrypted Data
This Binary field contains the encrypted track data for track 2.
Track 3 Encrypted Data
This Binary field contains the encrypted track data for track 3.
MagnePrint Status
This Binary field represents 32 bits of MagnePrint status information. Each character represents
4 bits (hexadecimal notation). For example, suppose the characters are: “A1050000”:

This four byte field contains the MagnePrint status. The MagnePrint status is in little endian
byte order. Byte 1 is the least significant byte. Byte 1 LSB is status bit 0. Byte 4 MSB is status
bit 31. MagnePrint status is defined as follows:
Bit 0
= This is a MagnePrint-capable product (usage M)
Bits 1-15
= Product revision & mode (usage R)
Bit 16
= STATUS-only state (usage S)
Bit 17
= Noise too high or “move me” away from the noise source (used only in
STATUS) (usage N)
Bit 18
= Swipe too slow (usage L)
Bit 19
= Swipe too fast (usage F)
Bit 20
= Unassigned (always set to Zero)
Bit 21
= Actual Card Swipe Direction (0 = Forward, 1 = Reverse) (usage D)
Bits 22-31 = Unassigned (always set to Zero)
If the Enable/Disable MagnePrint property is set to disable MagnePrint, this field will not be
sent.
Encrypted MagnePrint Data
This 56 byte Binary field contains the MagnePrint data. After decryption, the final two bytes
should be discarded leaving the 54 byte MagnePrint data. The least significant bit of the first
byte of data in this field corresponds to the first bit of MagnePrint data. If the Enable/Disable
MagnePrint property is set to disable MagnePrint, this field will not be sent.
Device Serial Number
This Simple ASCII field contains the device serial number. The device serial number is a NUL
(zero) terminated string. So the maximum length of the device serial number, not including the
