![]() Those cards with microcontroller chips can perform on-card processing functions and can manipulate information in the chip's memory. ![]() ![]() Smart cards are designed to be tamper-resistant and use encryption to provide protection for in-memory information. The chip on a smart card can be either a microcontroller or an embedded memory chip. They connect to a reader either by direct physical contact (also known as chip and dip) or through a short-range wireless connectivity standard such as radio-frequency identification ( RFID) or near-field communication ( NFC). Smart cards are typically the same size as a driver's license or credit card and can be made out of metal or plastic. A smart card is a physical card that has an embedded integrated chip that acts as a security token.
