A chip card, smart card, or integrated circuit card (ICC), is in any pocket-sized card with surrounded integrated circuits which can procedure data. This implies that it can obtain input which is processed - by way of the ICC applications - and delivered as an output. There are two wide classes of ICCs. Memory cards hold merely non-volatile memory storage mechanism, and possibly some exact security logic. Microprocessor cards hold volatile memory and microprocessor mechanism.

By smartcards also is a form of strong security verification for single sign-on contained by large organizations and companies .
