What Is a Smart Card Reader?
A smart card reader is a device specifically designed for interfacing with smart cards, which are plastic cards embedded with a microprocessor. These cards find widespread use across a multitude of applications, including bank cash cards, transportation fare systems, identification documentation, and access control mechanisms. They facilitate both contact and contactless interactions through physical connections and near-field communication (NFC) technology, respectively.
Beyond mere data retrieval, smart card readers are also capable of writing information onto the card itself. This dual functionality allows for a range of operations, such as personal information updates, balance top-ups, and adjustments to security settings. The use of sophisticated encryption methods further ensures the secure transmission and storage of data on smart cards.
