Magnetic Stripes

Magnetic stripes are thin bands of magnetic material found on the back of cards, like credit or debit cards. They store data by organizing tiny magnetic particles in specific patterns. When swiped through a card reader, the reader detects these patterns and translates them into information like account numbers or transaction details. This technology enables secure, fast transactions in various settings, including stores and ATMs. However, magnetic stripes are vulnerable to fraud if copied, which has led to increased use of more secure methods, such as chip technology and contactless payments.
