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. Using smart cards is also a form of strong security authentication for single sign-on within large companies and organizations.
