Encoding magnetic stripes
A magnetic stripe is the dark band/stripe which is featured on the reverse of a bank PVC card. The stripe is made up of tiny magnetic particles embedded in a resin and attached to the blank card.
Process
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.
Coercitivity
The coercitivity refers to the strength of a magnetic field required to edit data encoded on a magnetic stripe. There are two types of magnetic stripes with different levels of coercitivity:
- The HiCo (High Coercitivity) magnetic stripes offer a higher level of security against potential damages from third-party magnetic fields
- LoCo stripes (Low Coercitivity) are more sensitive to third-party magnetic fields
