Encoding magnetic strip

Magnetic stripe cards include a magnetic stripe on the back, which are used to encode data. The stripe is comprised of iron particles in a plastic film. Magnetic stripe cards are one of the most common types used. And although there are other options , magnetic stripe cards have many benefits.

Arduino Magnetic Stripe Decoder : 4 Steps (with Pictures) - Instructables

The stripe is made up of tiny magnetic particles embedded in a resin. During the encoding process, these particles are magnetized in a direction which is oriented either towards the North or the South pole. Each character on the stripe is encoded with sets of 1s and 0s. The polarity of the magnetic particles is changed to reflect each of those bits. Changing the magnetization of each particle on the stripe helps encode the binary information that will eventually be decoded by an appropriate reader. The coercitivity refers to the strength of a magnetic field required to edit data encoded on a magnetic stripe.

A magnetic stripe card is a type of card capable of storing data by modifying the magnetism of tiny iron-based magnetic particles on a band of magnetic material on the card. The magnetic stripe, sometimes called swipe card or magstripe , is read by swiping past a magnetic reading head. Magnetic stripe cards are commonly used in credit cards , identity cards , and transportation tickets. Magnetic recording on steel tape and wire was invented in Denmark around for recording audio. In , IBM used the magnetic tape idea to develop a reliable way of securing magnetic stripes to plastic cards, [2] under a contract with the US government for a security system.
