Magstripes come in two main varieties: high-coercivity (HiCo) at 4000 Oe and low-coercivity (LoCo) at 300 Oe, but it is not infrequent to have intermediate values at 2750 Oe. High-coercivity magstripes require higher amount of magnetic energy to encode, and therefore are harder to erase. HiCo stripes are appropriate for cards that are daily used, such as a credit card.attendance tracking card, library cards, employee ID cards and Membership Loyalty Card. Low-coercivity magstripes require a lower amount of magnetic energy to record, so the card writers are much cheaper than machines which are capable of recording high-coercivity magstripes. However, LoCo cards are much easier to erase and have a shorter lifespan. Typical LoCo applications include hotel room keys, time and attendance tracking, bus/transit tickets and season passes for theme parks. A card reader can read either type of magstripe, and a high-coercivity card writer may write both high and low-coercivity cards (most have two settings, but writing a LoCo card in HiCo may sometimes work), while a low-coercivity card writer may write only low-coercivity cards.
In fact, usually low coercivity magnetic stripes are a light brown color, and high coercivity stripes are nearly black; exceptions include a proprietary silver-colored formulation on transparent American Express cards. High coercivity stripes are resistant to damage from most magnets likely to be owned by consumers. Low coercivity stripes are easily damaged by even a brief contact with a magnetic purse strap or fastener. Because of this, virtually all bank cards today are encoded on high coercivity stripes despite a slightly higher per-unit cost.
Magnetic stripe cards are used in very high volumes in the mass transit sector, replacing paper based tickets with either a directly applied magnetic slurry or hot foil stripe. Slurry applied stripes are generally less expensive to produce and are less resilient but are suitable for cards meant to be disposed after a few uses.
