CARD ENCODE TYPE

This one byte value indicates the type of encoding that was found on the card. The following
table defines the possible values.
Value Encode Type
0 ISO/ABA
1 AAMVA
2 CADL
3 Blank
4 Other
5 Undetermined
6 None

TRACK DATA

If decodable track data exits for a given track, it is located in the track data field that corresponds
to the track number. The length of each track data field is fixed at 110 bytes, but the length of
valid data in each field is determined by the track data length field that corresponds to the track
number. Track data located in positions greater that the track data length field indicates are
undefined and should be ignored. The HID specification requires that reports be fixed in size,
but the number of bytes encoded on a card may vary. Therefore, the Input Report always
contains the maximum amount of bytes that can be encoded on the card and the number of valid
bytes in each track is indicated by the track data length field. The track data is decoded and
converted to ASCII. The track data includes all data starting with the start sentinel and ending
with the end sentinel.

TRACK 1 DATA

This field contains the decoded track data for track 1.

TRACK 2 DATA

This field contains the decoded track data for track 2.

TRACK 3 DATA

This field contains the decoded track data for track 3.
Description
ISO/ABA encode format
AAMVA encode format
CADL encode format
The card is blank.
The card has a non-standard encode format. For example,
ISO/ABA track 1 format on track 2.
The card encode type could not be determined because no
tracks could be decoded.
No decode has occurred. This type occurs if no magnetic stripe
data has been acquired since the data has been cleared or
since the device was powered on. This device only sends an
Input report when a card has been swiped so this value will
never occur.
