High coercivity magnetic stripes are usually black and made of barium ferrite. Hence, low coercivity magnetic stripes are easier to encode information on, and easier to erase information on. Therefore high coercivity magnetic stripes contain information that is more difficult to erase, and they have a practical use for cards that need a long life. It follows that high coercivity material is more difficult to encode information on. Typically, there is low coercivity and high coercivity.

Coercivity is the measure of the resistance of a magnetic material to becoming unmagnetized. Then, the solution hardens and is either laminated or stamped onto a card.ĭifferent types of magnetic materials used on cards have different coercivity. Then, it is combined with a plastic-type of material in a liquid consistency. Well, a type of metal (usually iron oxide or barium ferrite) is ground up into a fine powder. You must be wondering, what is this magnetic stripe made of, and how did it get there? Magnetic material (also known as ferromagnetic material) is a material that retains properties of a magnet even after an external magnetic field is removed (all N-S poles are aligned in the same direction). Essentially, this stripe is a very thin layer of magnetized material that has information stored on it. you would notice a narrow black or brown stripe on the back of it. If you look at your student ID, ATM car, or subway ticket etc. Magstripes - Credit to Plastic Card Printing Canada LLC - on Wordpr These types of cards are becoming more and more popular across college campuses worldwide. That means that this one card can be used to access different information and perform many tasks such as buying food at different venues, gaining access to buildings, and has actual money stores on it. At Vassar, every student has a “VCard” which is a one-swipe magnetic stripe card. These include access cards (let you into buildings), bank cards (transaction processing), phone card (prepaid PIN cards), Credit or Debit Cards (revolving accounts that include a purchase transaction), and health cards (store personal medical history). Within these specific markets there are a vast variety of different types of magstripe cards. Some of these markets include Financial Services, Travel and Transportation, Health Insurance, and Education. Magstripes are used in a lot of different markets in modern day living. Magnetic Stripe Reader - credit to product image on DIY Trading Future uses of the magstripe could broaden into official documents such as passports, and one-swipe cards (a magnetic stripe card that has multiple purposes) are starting to become used more and more on college campuses throughout the country. These cards can have greater capacity than magstripe cards and have have broader information carrying capacities, that can be added or deleted, as well as being able to accomplish some more complicated tasks such as data encryption.

In 2011, financial and transit cards constitute the largest group of cards with magstripes, and they all follow the ISO standards to “ensure read reliability world wide.” Another more modern type of swipe card is the “smart card.” These are more secure than magstripe cards they have a chip on the card that prevents the information from being damaged or stolen.

However, one of the most important dates for magstripes was 1970, where the standards were established for credit cards (which were first issued in 1951) and magnetic stripes became used. These “smart cards” were first patented in France in 1974. In the late 1960s the USA was using magnetic stripes in cards for the Bay Area Rapid Transit. The first official documented use of magstripes on cards is from the London Transit Authority who, in the early 1960s, installed magstripes on cards for the London Underground.

Magnetic card readers capable of decoding the data formats used for credit cards are available pretty cheaply on the Internet, but for arbitrary formats you might need the raw data on the card. TI-59 magnetic card (saves programs from programmable calculator).
