smart card

A smart card is a small, physical card similar to a credit card that contains an embedded microchip. This microchip securely stores data and can process information, enabling it to perform functions like secure identification, authentication, or transactions. Smart cards are commonly used for banking, access control, public transportation, and identification purposes. They offer enhanced security because the data stored is difficult to clone or tamper with, making them more secure than traditional magnetic stripe cards. The chip can communicate with compatible systems to verify identity, authorize payments, or grant access, ensuring efficient and safe interactions.
