Magnetic Stripe Readers

A Magnetic Stripe Reader (MSR) is a device used to read information stored on the magnetic stripe of a card. These stripes are found on credit cards, debit cards, ID cards, access control cards, and transportation cards. The reader scans the data encoded in the stripe when the card is swiped through the slot.

How Magnetic Stripe Readers Work

The card is swiped through the reader.
The magnetic stripe, which contains encoded data, is read by the device.
The reader decodes the information and sends it to a computer system for verification or processing.
