Information about credit card magnetic stripe and how it works

The credit card magnetic stripe or magstripe as they are sometimes called carries loads of information. Each stripe is made up of iron based magnetic particles that are in a plastic film with each one being a very small bar magnetic of about 20 millionths of an inch. These magnetic stripes are able to have information placed on them because each magnet can be magnetised in the direction of the north or south pole. Each magstripe has three tracks that is one-tenth of an inch wide and each track contains unique data.

Before describing how a magnetic card reader works, look at how data is stored on a magnetic card and the format of data storage collected.

“Two-Frequency, Coherent Phase Recording” is used for encoding magnetic cards. It is also called F/2F sampling-encoding. By using combined data and clock bits, self-clocking is achieved.

Now that it is understood how data is stored on a magnetic card, it is a bit easier to build on that foundation to gain an understanding of how the reader actually works.

The magnetic card reader uses a specific component to read data from a magnetic card, which is referred to as the read head. The magnetic card reader is a microcontroller-based device. The read heads contain signal amplifiers and line drivers. All modern magnetic read heads contain integrated F/2F bit recovery circuitry and interface with the host controller.

The magnetic card reader is a microcontroller-based device and has been programmed for a specific application. That program simply reads the card in a forward direction in a simple data format or it can be complex enough to read the card in any direction with a corresponding encoding format.

Some more information on Magnetic strip

Magnetic strip have the encrypted data of you card Number etc. on that, when it is getting swiped in the POS (point of sales) machine it reads and transmit it through the telephone line connection to the International gateway service provider Visa or mastercard etc.

Now the Magnetic strip is been replace with a chip ( mandatory as per RBI for all CREDIT CARDS). THE chip is just like that of a SIM issued by the Telecom service provider. for double authentication PIN or OTP is a must.
