What does a card reader do?
A card reader is a device that can read information encoded in magnetic stripes or microchips on various cards, such as credit cards, debit cards, ID cards, and access cards.
When a card is swiped, inserted, or placed near the card reader, it reads the data stored on the card and connects with a centralized system to verify or authenticate the cardholder's identity or make a transaction authorization.
Card readers are widely used in various applications, including point-of-sale systems at retail stores, ticket vending machines, parking meters, and automated teller machines, just to name a few. The technology provides a quick, convenient, and secure way for individuals and businesses to manage financial transactions or verify identity.
