As ido general rule, data on Magnetic Cards conforms to the encoding format for financial transaction cards ISO Lower-density data recorded on track 2 contains only the account number and expiration date. Full copies of these standards can be pruchased from www.

Other custom utilizations are also possible and appropriate. The data is read least significant bit first.

Magnetic Strip Encoding Standards. The information below is abstracted from these standards. Track 3, originally an alternate numeric-only track, is no longer used in the Banking and Credit Card format. Account Number Name Expiration Date. 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.


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.

This table is only an overview of what data fields are contained on the three tracks of a 7811–4 coded driver’s license. Account Number Expiration Date.

Physical Dimensions of Cards: 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. In the early years of Magnetic Stripe technology, data was recorded at lower density to increase read-reliability. Below will be found a brief synopsis of some Magnetic Strip Encoding Standards.

Tracks 1 and 3 read alphanumeric data at bpi, while track 2 reads numeric data only at 75 bpi. Readers with both track 1 and 2 are recommended for acquiring Credit Card data since isk permits the authorization isoo 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.


Physical Plastic Card 2.

Information Content including control characters. Note also the redundancy:. Call Abacus 21 for further details. 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 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 Specification – No longer in use. Site 7181-4 Upcoming Events. Recording Density bits per inch.

Track 1 contains the ixo name in addition to the account number and expiration date recorded at higher density. ISO defines the physical characteristics of the card.
