A magnetic stripe on the back of a credit card or gift card store small bits of information. Magnetic card readers retrieve that information when the credit card is used to make a purchase. The magnetic stripe, or magstripe, is made up of tiny iron-based magnetic particles in a plastic-like film. Each particle is a small bar magnet about 20 millionths of an inch long. Magnetic stripe cards are on credit cards<\/strong>, identity cards<\/strong>, gift cards<\/strong>, and point-of-sale-activation (POSA) cards<\/strong>.<\/p>\n

Each stripe contains three tracks. Each track is basically a single physical (but invisible) line on the magnetic strip and must meet ISO standards when encoding these tracks. Information redundancy has also been built in on a magnetic stripe. This design redundancy means that if the first track of the magnetic stripe is damaged, the second track can still carry enough information to use the credit card to make purchases. Point-of-sale card readers almost always read track 1, or track 2, and sometimes both, in case one track is unreadable.<\/p>\n

Point-of-sale equipment is electronics gadgetry that is programmed to perform specific tasks – such as reading magnetic stripes. Examples of cards adhering to these standards include ATM cards, bank cards (credit and debit cards including VISA and MasterCard), gift cards, loyalty cards, driver’s licenses, telephone cards, membership cards, electronic benefit transfer cards (e.g. food stamps), and nearly any application in which value or secure information is not stored on the card itself. Many video game and amusement centers now use debit card systems based on magnetic stripe cards.<\/p>\n

Magstripes come in two varieties: high-coercivity (Hi\/Co) and low-coercivity (Lo\/Co). High-coercivity magstripes are harder to erase, and therefore are appropriate for frequently-used cards or which those that need to have a long life. Low-coercivity magstripes require a lower amount of magnetic energy to record, and hence the card writers are much cheaper than machines which are capable of recording high-coercivity magstripes. Both high-coercivity and low-coercivity cards have up to three tracks for encoding.<\/p>\n

The advantage of high coercivity is that it is harder to encode the information on the stripe. This advantage also means that it is more difficult to erase the data, making accidental erasure infrequent. It is still possible to wipe the information, but ordinary household magnets are not usually powerful enough.<\/p>\n

\"\"<\/p>\n

Card Track One<\/strong>
\nTrack one is the only track that contains the name of the account holder. This track also contains the information of the card issuing bank, including the credit account number, cardholder billing address, country code for the account, expiration date of the account and a three digit service code. The service code communicates to a buyer how the card must be billed, if the buyer has international purchasing privileges or just national purchasing privileges and whether or not a PIN number is required for purchase approval. Track 1 holds 79 alpha\/numeric characters.<\/p>\n

Card Track Two<\/strong>
\nTrack two in the magnetic stripe of a credit or debit card stores very similar information to track one with several important differences. Track two only stores numeric code, whereas track one stores alphanumeric code. This means track two cannot store information containing letters, only numbers. Track two may also include the primary account number and discretionary data like PIN number verification and the criteria for purchase approval. According to the Plastic Rewards website, one purpose of track two is to review the information sent from the credit card to the scanner to ensure all the information is read correctly and no errors occur. Track 2 stores 40 numeric characters.<\/p>\n

Card Track Three<\/strong>
\nNational bank card issuers do not use this track three, and in fact, it mostly unused. Sometimes Track three is not even present on the card, as in the case of a two-track magnetic stripe. Retailers and other businesses may use Track three for purchasing data storage including any PIN required to access the account and total available credit. No standard exists for data stored on track three as exists with tracks one and two. Some credit cards with very narrow magnetic strips do not contain a third data track. Track 3 holds 107 numeric characters.<\/p>\n

To produce your magnetic stripe cards correctly:<\/strong><\/p>\n

    \n
  1. We need to know which type of magnetic stripe: \u00a0low coercivity (LoCo) or high coercivity (HiCo)<\/li>\n
  2. Indicate which track to encode the data (usually track 1 or track 2, or both 1 & 2)<\/li>\n
  3. A data file (Excel, .csv, .txt) with the information that we need to encode onto the magnetic stripe<\/li>\n<\/ol>\n

    It is best to have all your information at the time you place your order. Fortunately, it’s easy to obtain \u2013 contact your POS system provider or technical support department.<\/p>\n","protected":false},"excerpt":{"rendered":"
