A plastic card makes life much easier, providing a wide range of opportunities for their use, allows you to quickly and easily receive cash or pay for purchases, including without queues at special devices - self-service kiosks - to pay for utilities.
Magnetic stripe card - a plastic card with a special magnetic stripe on the back for storing information. Information is recorded on the magnetic stripe by magnetizing tiny ferrimagnetic (iron-based) particles that are on the surface of the magnetic stripe; information is read using a special magnetic head.
The parameters of the magnetic card are regulated by the international ISO standards.
Most cards contain a 9.52 mm wide magnetic stripe. The stripe is usually located 5.66 mm from the edge of the card. The strip has three tracks of 2.79 mm.
Standardized magnetic stripe cards work with most checkout counters and general-purpose computers.
In addition to its dimensions, the magnetic strip is characterized by the value (Unit of measurement - Ampere / meter) - the value of the magnetic field strength, which is necessary for the complete demagnetization of a ferro- or ferrimagnetic substance.
According to the magnitude of the coercive force, the stripes are divided into:
However, cards with a magnetic stripe have their own significant drawback - they are poorly protected from the actions of qualified intruders who are capable of forging cards using special devices and withdrawing money from an ATM using counterfeit plastic cards.
Microprocessor cards - chip cards or smart cards - provide a high degree of protection against counterfeiting .
