  2. 2. Crafts In-depth IntroductionIntroduction - What is Magnetic stripe?A magnetic stripe is the black or brown stripe that you see on your credit card, or maybe the back ofyour airline ticket or transit card. The stripe is made up of tiny magnetic particles in a resin. The particlesare either applied directly to the card or made into a stripe on a plastic backing which is applied to thecard.
  3. 3. Crafts In-depth IntroductionMagnetic stripe coercivityMagstripes come in two main varieties: high-coercivity (HiCo) at 4000 Oe and low-coercivity (LoCo) at300 Oe but it is not infrequent to have intermediate values at 2750 Oe. High-coercivity magstripes areharder to erase, and therefore are appropriate for cards that are frequently used or that need to have along life. Low-coercivity magstripes require a lower amount of magnetic energy to record, and hence thecard writers are much cheaper than machines which are capable of recording high-coercivitymagstripes. A card reader can read either type of magstripe, and a high-coercivity card writer may writeboth high and low-coercivity cards (most have two settings, but writing a LoCo card in HiCo maysometimes work), while a low-coercivity card writer may write only low-coercivity cards.In practical terms, usually low coercivity magnetic stripes are a light brown color, and high coercivitystripes are nearly black; exceptions include a proprietary silver-colored formulation on transparent
  4. 4. Crafts In-depth IntroductionAmerican Express cards. High coercivity stripes are resistant to damage from most magnets likely to beowned by consumers. Low coercivity stripes are easily damaged by even a brief contact with amagnetic purse strap or fastener. Because of this, virtually all bank cards today are encoded on highcoercivity stripes despite a slightly higher per-unit cost.Magnetic stripe cards are used in very high volumes in the mass transit sector, replacing paper basedtickets with either a directly applied magnetic slurry or hot foil stripe. Slurry applied stripes are generallyless expensive to produce and are less resilient but are suitable for cards meant to be disposed after afew uses.

  7. 7. Crafts In-depth IntroductionHow does the magnetic stripe workThe end-user defines the requirements for the magnetic stripe including the signal amplitude expected,the coercivity of the stripe, the encoding method and the bit density. The card manufacturer uses thefirst two points to select the type of magnetic material to use. The system designer is concerned with allfour of the parameters.As explained above, the stripe is made from many small particles bound together in a resin. The densityof the particles in the resin is one of the controlling factors for the signal amplitude. The more particlesthere are, the higher the signal amplitude. The density (or loading) combined with the thickness give amethod for controlling the amplitude. Signal amplitude is important because it defines the design of thereaders for the cards. Standards exist (ISO/IEC 7811) which define the signal amplitude for cards thatare used in the interchange environment (such as banking). By conforming to these standards, a user
  8. 8. Crafts In-depth Introductionensures that the magnetic stripe can be read in any financial terminal world wide.The bit density of the information is selected based on the user requirement. The ISO/IEC standards(7811) give requirements for bit density for cards used in the interchange environment. These standardsdefine tracks one and three as 210 bits per inch and track two as 75 bits per inch. The bit density inconjunction with the data format dictate how much data is encoded on each track.
  9. 9. Crafts In-depth IntroductionBenefits1. Added security in view of the fact that it is not in human readable form.2. Immune to contagion with dirt, water, oil, moisture, etc.3. Data can be customized or rewritten.4. High data capability on the subject of bar codes.5. No moving components, physically robust.6. Well-known standards.7. No consumables necessary for writing or rewriting.
