Track 1, Track 2 and Track 3 Encrypted Data includes the Start and End Sentinel that were
decoded from the card.
All fields with the format P# are programmable configuration property numbers. They are
described in detail later in this document.
Reader Encryption Status
This two byte Binary field contains the Encryption Status. The Reader Encryption Status is sent
in big endian byte order. Byte 1 is the least significant byte. Byte 1 LSB is status bit 0. Byte 2
MSB is status bit 15. The Reader Encryption Status is defined as follows:
Bit 0 = DUKPT Keys exhausted
Bit 1 = Initial DUKPT key Injected, always set to One
Bit 2 = Encryption Enabled, always set to One
Bit 3 = Authentication Required
Bit 4 = Timed Out waiting for user to swipe card
Bit 5 = Encrypting IntelliHead Communication Error – Message too Short
Bit 6 = Encrypting IntelliHead Communication Error – Wrong Message Type
Bit 7 = Key Synchronization Error (only on units equipped with Encrypting
IntelliHead)
Bit 8 = Encryption Counter Expired
Bits 9–15 = Unassigned (always set to Zero)
