USB MagnePrint Swipe Reader with Encryption
20
Value Encode Type Description
0 ISO/ABA ISO/ABA encode format
1 AAMVA AAMVA encode format
2 CADL CADL encode format. Note that this reader can only read track 2 for this
format. It cannot read tracks 1 and 3. However, this format is obsolete.
There should no longer be any cards in circulation that use this format.
California is now using the AAMVA format.
3 Blank The card is blank.
4 Other The card has a non-standard encode format. For example, ISO/ABA
track 1 format on track 2.
5 Undetermined The card encode type could not be determined because no tracks could
be decoded.
6 None 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.
Track Data
If decodable track data exists 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 112 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 than 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.
Card Status
This one byte field is reserved for future use. It is currently not used on this reader.
