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. Tracks 1 and 3 read alphanumeric data at bpi, while track 2 reads numeric data only at 75 bpi.

Account Number Expiration Date. Below will be found a brief synopsis of some Magnetic Strip Encoding Standards.

Low density data is still recorded on track 2 for compatibility with older-technology readers and provide redundancy when reading with newer-technology readers. Magnetic Strip Encoding Standards. In the early years of Magnetic Stripe technology, data was recorded at lower density to increase read-reliability. Account Number Name Expiration Date.

The data is read least significant bit first. ISO Specification – No longer in use. The information below is abstracted from these standards. Track 1 contains the customer’s name in addition to the account number and expiration date recorded at higher density. 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.

Information Content including control characters. This table is only an overview of what data fields are contained on the three tracks of a magnetically coded driver’s license. Note also 78811-4 redundancy:. 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.

Other custom utilizations are also possible and appropriate. Track 3, originally an alternate numeric-only track, is no longer used in the Banking and Credit Card format. Physical Plastic Card 2.

Call Abacus 21 for further details. Track 1 and 2 of the Driver’s License Magnetic Stripe format conform to the original formatting standards used by the Banking and Credit Card industry. ISO defines the physical characteristics of the card. Recording Density bits per inch. 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.
