The magnetic stripe is the classic feature of a Plastic card. The stripe is covered with a magnetic metallic oxide - it can be encoded and read. Magnetic stripes are cheap data carrier for universal use. The encoded data can be changed in contrary to a fix printed individual barcode. The price advantage in comparison to other data carrier such as Contact- or RFID chips and the variability of data makes the magnetic stripe a widely application in many fields. There are two different types of magnetic stripes. The resistance against deleting (coercitivity) makes the difference. The capacity is the same in both types. LoCo coercivity: 300 Oersted* colour: brown or black prone to magnetic perturbation HiCo coercitivity: 2750 Oersted* or 4000 Oersted* colour: black relatively resistant against magnetic perturbation *Oersted (Oe) is the unit for magnetic field strength Both types do have the same measures and are standardized acc. to DIN 7811. Standard Plastic cards with magnetic...
