IC卡, or Integrated Circuit Card, is a type of smart card that contains an embedded microchip. This chip can store and process data, making IC cards useful for various applications, such as electronic payments, access control, and public transportation. They are commonly used in many countries for secure transactions and identification. These cards can be contact or contactless, allowing users to tap or insert them into card readers. IC卡 technology enhances security by encrypting data and requiring authentication, making them a popular choice for banking, transportation systems, and identity verification.
