This table is only an overview of what data fields are contained on the three tracks of a magnetically coded driver’s license. Other custom utilizations are also possible and appropriate. Track 1 contains the customer’s name in addition to the account number and expiration 8711-4 recorded at higher density.

Note also the redundancy:. Recording Density bits per inch. The information below is abstracted from these standards.

Information Content including control characters. Tracks 1 and 3 read alphanumeric data at bpi, while track 2 reads numeric data only at 75 bpi.

Character Configuration including parity bit. Low density data is still recorded on track 2 for compatibility with older-technology readers and provide redundancy when reading with newer-technology readers. Full copies of these standards can be pruchased from www. Below will be found a brief synopsis of some Magnetic Strip Encoding Standards. While the information contained on each track may be only slightly different, the field order, field lengths, and method of field separation and termination differs significantly.

The data is read least significant bit first. In the early years of Magnetic Stripe technology, data was recorded at lower density to increase read-reliability.

ISO Specification – No longer in use. In order to encode the additional alpha-numeric information required on the Driver’s License, the specification was revised to permit alpha-numeric information to be encoded on track 3.

Track 3, originally an alternate numeric-only track, is no longer used in the Banking and Credit Card format. Lower-density data recorded on track 2 contains only the account number and expiration date. Track 1 and 2 of the Driver’s Ios Magnetic Stripe format conform to the original formatting standards used by the Banking and Credit Card industry.

As a general rule, data on Magnetic Cards conforms to the encoding format for financial transaction cards ISO Note from the table below that Magnetic Stripe Readers used for acquiring Credit Card data need only to read tracks 1 or 2 from the card. Physical Plastic Card 2. Readers with both track 1 and 2 are recommended for acquiring Credit Card data since redundancy permits the authorization process to compare account information on both tracks and also fallback to the lower density track data if the reader is unable to decode track 1 due to damaged track data on the card.
