Shak In the early years of Magnetic Stripe technology, data was recorded at lower density to increase read-reliability. The information below is abstracted from these standards. Life cycle A standard is reviewed every 5 years 00 Preliminary.
No consideration is given within iao document to the amount of use, if any, experienced by the card prior to test. Using either system is correct but intermixing or reconverting values can result in errors. Lower-density data recorded on track 2 contains only the account number and expiration date.
Tracks 1 and 3 read alphanumeric data at bpi, while track 2 reads numeric data only at 75 bpi. Account Number Name Expiration Date. Information Content including control characters. The embossed characters are intended for transfer of data either by use of imprinters or iwo visual or machine reading. Monday to Friday — It takes into consideration both human and machine aspects and states minimum requirements.
Character Configuration including parity bit. Physical Plastic 2. Track 3, originally an alternate numeric-only track, is no longer used in the Banking and Credit Card format. ISO Specification — No longer in use. 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.
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. Note from the table below that Magnetic Stripe used for acquiring Credit Card data need only to read tracks 1 or 2 from the card.
The original design was made using the Imperial measurement system. Note also the redundancy:. Other custom utilizations are also possible and appropriate. This document specifies requirements for embossed characters on identification cards. The data is read least significant bit first. Full copies of these standards can be pruchased from www. Site Search Upcoming Events. Account Number Expiration Date. ISO defines the physical characteristics of the card. Below will be found a brief synopsis of some Magnetic Strip Encoding Standards.
It is the purpose of this document to provide criteria to which cards shall perform. Magnetic Strip Encoding Standards. As a general rule, data on Magnetic Cards conforms to the encoding format for financial transaction cards ISO Failure to conform to specified criteria is negotiated between the involved parties. Call Abacus 21 for further details. Physical Dimensions of Cards:.
