The data is read least significant bit first. Recording Density bits per inch. Information Content including control characters. Physical Dimensions of Cards: Full copies of these standards can 7811-4 pruchased from www. Site Search Upcoming Events.

In order to encode the additional alpha-numeric information required on isl Driver’s License, the specification was revised to permit alpha-numeric information to be encoded on track 3. Magnetic Strip Encoding Standards. Character Configuration including parity bit. Track 1 contains the customer’s name in addition to the account number and expiration date recorded at higher density.

Account Number Name Expiration Date.


Physical Plastic Card 2. 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 isi only an overview of what data fields are contained on the three tracks of a magnetically coded driver’s license.

Account Number Expiration Date. Track 3, originally an alternate numeric-only track, is no longer used in the Banking and Credit Card format.

As a general rule, data on Magnetic Cards conforms to the encoding format for financial transaction cards ISO Track 1 and 2 of the Driver’s License Magnetic Izo format conform to the original formatting standards used by the Banking and Credit Card industry. Note also the redundancy:. Other custom utilizations are also possible and appropriate.

The information below is abstracted from these standards. Tracks 1 and 3 read alphanumeric data at bpi, while track 2 reads numeric data only at 75 bpi. 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.

ISO defines the physical characteristics of the card. Lower-density data recorded on track 2 contains only the account number and expiration date. In the early years of Magnetic Stripe technology, data was recorded at lower density to increase read-reliability.

ISO Specification – No longer in use. 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. 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 isp track data if the reader is unable to decode track 1 due to damaged track data on the card.

Below will be found a brief synopsis of some Magnetic Strip Encoding Standards. Call Abacus 21 for further details.
