Magnetic stripes come in two versions, the normal credit card version and the high-coercivity (HiCo) version. The HiCo version enhances reliability by reducing the chances the data being deleted or damaged unintentionally. Coercivity is defined as the strength of the flux reversals in the magnet, or in other words the resistance of the material to demagnetization. This is the most important characteristic in determining what kind of material to use as the stripe. When a magnet is demagnetized in magnetic stripe, the data encoded is lost or distorted. Therefore, the higher the coercivity of the material, the less chance the magnetic stripe in becoming damaged. However, the higher the coercivity of a material, the more expensive it is.
The unit of measure for coercivity is Oersted (Oe). The lower the Oersted value, the lower the coercivity, vice versa. The typical range of coercivity of the material used is from 300 Oe to 4000OE
