Track 1 and 2 of the Driver’s License Magnetic Stripe format conform to the original formatting 781-4 used by the Banking and Credit Card industry. 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. Track 1 contains the customer’s name in jso to the account number and expiration date recorded at higher density. Note also the redundancy:.

ISO/IEC – Wikipedia

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. Account Number Expiration Date. As a general rule, data on Magnetic Cards conforms to the encoding format for financial transaction cards ISO In the early years of Magnetic Stripe technology, data was recorded at lower density to increase read-reliability.


Character Configuration including parity bit.

Track 3, originally an alternate numeric-only track, is no longer used in the Banking and Credit Card format. Recording Density bits per inch.

Physical Plastic Card 2. Other custom utilizations are also possible and appropriate.

The data is read least significant bit first. ISO Specification – No longer in use.

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

Full copies of these standards can be pruchased from www. Physical Dimensions of Cards: The information below is abstracted from these standards. Lower-density data recorded on track 2 contains only the account number and expiration date. ISO defines the physical characteristics of the card.


ISO/IEC 7811-4:1995

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. Account Number Name Expiration Date.

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. Site Search Upcoming Events. Below will be found a brief synopsis of some Magnetic Strip Encoding Standards.
