TRACK 3 DECODE STATUS

Bits 7-1 0

Value Reserved Error

This is a one-byte value, which indicates the status of decoding track 3. Bit position zero

indicates if there was an error decoding track 3 if this bit is set to one. If it is zero, then no error

occurred. If a track has data on it that is not noise, and it is not decodable, then a decode error is

indicated. If a decode error is indicated, the corresponding track data length value for the track

that has the error will be set to zero and no valid track data will be supplied.

TRACK 1 DATA LENGTH

This one-byte value indicates how many bytes of decoded card data are in the track 1 data field.

This value will be zero if there was no data on the track or if there was an error decoding the

track.

TRACK 2 DATA LENGTH

This one-byte value indicates how many bytes of decoded card data are in the track 2 data field.

This value will be zero if there was no data on the track or if there was an error decoding the

track.

TRACK 3 DATA LENGTH

This one-byte value indicates how many bytes of decoded card data are in the track 3 data field.

This value will be zero if there was no data on the track or if there was an error decoding the

track.

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 Description

0 ISO/ABA ISO/ABA encode format

1 AAMVA AAMVA encode format

2 CADL CADL encode format. Note that (after the June 2005 update)

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 However, this format is obsolete.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.
