card readers

Card readers are devices that capture information from cards, such as credit cards, ID cards, or access cards. They work by using magnetic stripes, chips, or RFID technology to read data from the card when it's swiped, inserted, or tapped. This data is then transmitted to a computer or payment system to authenticate the cardholder or process transactions. Card readers are commonly used in retail stores for payments, in offices for secure entry, and in various services that require identity verification. They enhance security and streamline processes in many sectors.
