Smart card is an integrated circuit card, which has the same appearance as a credit card and contains an integrated circuit chip card conforming to the ISO standard. It is also called "integrated circuit card" or "smart card" in English. It was invented by Frenchman Roland Moreno in 1974.
IC cards are formed by encapsulating integrated circuit chip modules with storage encryption and data processing capabilities in plastic substrates with the same size as credit cards.
