A smart card is one that has both a microprocessor and a memory chip,or only a memory chip with non-programmable logic. A micro processor card can add, remove, and alter data on the card, but a memory-chip card (such as pre-paid phone cards) can only perform a single action.
Smart cards are used for a variety of reasons, with credit cards and other forms of payment being the most common. Smart card use has increased in recent years as a result of the payment card industry's choice to use smart cards for the EMV payment card standard. Smart cards with short-range wireless connection can also be used as multifactor authentication tokens and contactless payment systems.
