Magnetic Stripe

The Magnetic Stripe — also known as the magstripe — is located on the back of credit, debit, and other types of payment cards. This stripe is made of magnetic particles that can be encoded with data. It usually contains the following information:

  • cardholder’s account number
  • card expiration date
  • a security code

When the card is swiped through a card reader, this data is read and transmitted for processing payments. While the magnetic stripe has been a key feature of payment cards for many years, it is gradually being replaced by more secure technologies such as EMV chips.

This is because the data stored on the magnetic stripe can be easily copied and used to create counterfeit cards. Nonetheless, magnetic stripe cards are still in use in many parts of the world, and merchants must be equipped to accept them.
