Magnetic Stripe Technology

Magnetic stripe technology, commonly used on credit and debit cards, encodes data on a thin strip of magnetic material. When the card is swiped through a reader, the device detects the magnetic signals, which represent information like account number and other details. This data is then transmitted to a processing system for verification and transaction completion. The stripe's magnetic material can be read and rewritten, but modern systems are increasingly replacing it with more secure options like chip or contactless payments. Overall, it provides a quick, convenient way to securely access financial information during transactions.
