Smart card

A smart card, chip card, or integrated circuit card (ICC), is defined as any pocket-sized card with embedded integrated circuits which can process information.

This implies that it can receive input which is processed - by way of the ICC applications - and delivered as an output. There are two broad categories of ICCs.

Memory cards contain only non-volatile memory storage components, and perhaps some specific security logic. Microprocessor cards contain volatile memory and microprocessor components.

The card is made of plastic, generally PVC, but sometimes ABS. The card may embed a hologram to avoid counterfeiting.
