Information Content including control characters. Character Configuration including parity bit.

Physical Dimensions of Cards: Lower-density data recorded on track 2 contains only the account number and 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. Track 1 contains the customer’s name in addition to the account number iwo expiration date recorded at higher density.

As a general rule, data on Magnetic Cards conforms to the encoding format for financial 7811-44 cards ISO Note also the redundancy:. Account Number Name Expiration Date. Account Number Expiration Date.

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

Tracks 1 and 3 read alphanumeric data at bpi, while uso 2 reads numeric data only at 75 bpi. Recording Density bits per inch.

The information below is abstracted from these standards. Below will be found kso brief synopsis of some Magnetic Strip Encoding Standards. 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.

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. ISO defines the physical characteristics of the card.

Other custom utilizations are also possible and appropriate. Call Abacus 21 for further details. Track 3, originally an alternate numeric-only track, is no longer used in the Banking and Credit Card format. This table is only an overview of what data fields are contained on the three tracks of a magnetically coded driver’s license.


ISO/IEC 7811-4:1995

In order to encode the additional alpha-numeric information required on the Driver’s License, the specification was revised to permit alpha-numeric 711-4 to be encoded on track 3. The data is read least significant bit first. ISO Specification – No longer in use.

Low density data is still recorded on track 2 for compatibility with older-technology readers and provide redundancy when reading with newer-technology readers. Physical Plastic Card 2.
