Track 1 requested (bit 6 = 1). Includes first instance of:
Tag 56 = Track 1 Equivalent
Tag 5F21 = Track 1, identical to the data coded
Track 2
requested (bit 5 = 1). Includes first instance of:
Tag 57 = Track 2 Equivalent (converted to alpha numeric format)
Tag 9F6B = Track 2 Data
Tag 5F22 = Track 2, identical to the data coded
Track 3
requested (bit 4 = 1). Includes first instance of:
Tag 58 = Track 3 Equivalent
Tag 5F23 = Track 3, identical to the data coded
PAN
requested (bit 7 = 1). Includes:
Tag 5A = PAN (converted to alpha numeric format)
Sentinels
For any found data element of Track1, Track2 or Track3, sentinels will be included or not
included according to the preferences set in bits 1, 2 and 3.
Compressed Numeric Elements
For any data element captured as compressed numeric, the following rules shall apply:
Padding (0xf) shall not be included
Center separators: 0xd shall be converted to 0x3d ("=")
Data shall be encoded as ASCII representation of binary data
example 0x123f = 0x313233 = "123" (ignore padding)
example 0x1234 = 0x31323334 = "1234"
example 0x123d456f = 0x3132333d343536 = "123=456"
Tag DFEF4C
If tag DFEF4B is set, tags DFEF4C will appear in transaction output.
This tag's 6-byte value provides the native lengths of tracks 1, 2, and 3, and the PAN (if
applicable). Two bytes are reserved for future use.
<Track 1 Length><Track 2 Length><Track 3 length><PAN length><RFU><RFU>
A length of 0 indicates track disabled in DFEF4B or data not available. This tag also serves as
an indicator of which data element was found first, when "Only First Element Found" is
enabled in DFEF4B.
