A Smart Card Reader is a device that allows users to read and interact with smart cards, which are plastic cards embedded with a microchip. These cards can store data securely and are commonly used for identification, payment, and access control. Smart card readers can connect to computers or other devices via USB, Bluetooth, or other interfaces, enabling secure transactions and data exchange. Smart card readers are widely used in various sectors, including banking, healthcare, and government. They enhance security by requiring authentication through the smart card, making it difficult for unauthorized users to gain access. Examples of smart cards include credit cards, ID cards, and employee badges.
