The data is read least significant bit first. Magnetic Strip Encoding Standards. Physical Plastic Card 2.

Lower-density data recorded on track 2 contains only the account number and expiration date. ISO 7181-4 – No longer in use. Below will be found a brief synopsis of some Magnetic Strip Encoding Standards.

Character Configuration including parity bit. Information Content including control characters. 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. Site Search Upcoming Events. 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 ido 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.

Call Abacus 21 for further details. Recording Density bits per inch.

ISO/IEC 7811

This table is only an overview of what data fields are contained on the three tracks of a magnetically coded driver’s license.

The information below is abstracted from these standards. ISO defines the physical characteristics of the card. Track 1 contains the customer’s name in addition to the account number isl expiration date recorded at higher density. Account Number Name Expiration Date. As a general rule, data on Magnetic Cards conforms to the encoding format for financial transaction cards ISO Account Number Expiration Date.

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. Low density data is still recorded on track 2 for compatibility with older-technology readers and provide redundancy when reading with newer-technology 7811. 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 is. Tracks 1 and 3 read alphanumeric data at bpi, while track 2 reads numeric data only at 75 bpi.

Physical Dimensions of Cards: 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.

In the early years of Magnetic Stripe technology, data was recorded at lower density 7811-4 increase read-reliability. Note also the redundancy:. Full copies of these standards can be pruchased from www.
