Magnetic Stripe Cards

Magnetic Stripe Card is commonly used for gift cards, loyalty cards, membership cards, credit cards, identity cards, and transportation tickets. Magnetic stripe cards are also used in access control as key cards, as well as on ID cards. They come in two main varieties: high-coercivity (HiCo) and low-coercivity (LoCo).Loco stands for 300oe while Hico stands for 2750oe.

There are up to three tracks on magnetic cards known as tracks 1, 2, and 3. Track 3 is virtually unused by the major worldwide networks, and often isn’t even physically present on the card by virtue of a narrower magnetic stripe. The minimum cardholder account information needed to complete a transaction is present on both track1 and track 2. Track 1 has a higher bit density (210 bits per inch vs. 75), is the only track that may contain alphabetic text, and hence is the only track that contains the cardholder’s name.
