Magnetic-stripe cards, which store a very small amount of information (most typically used to identify the owner) and have no processing capability of their own, can be thought of as primitive smart cards. A true smart card contains 80 or more times as much memory, and the microprocessor allows information to be read and updated every time the card is used. Contact cards, which must be swiped through card readers, are less prone to misalignment and being misread but tend to wear out from the contact; contactless cards, which are read by using radio-frequency identificationradio-frequency identification
(RFID), a technology that uses radio waves to transmit data and uniquely identify an animal, person, or thing. An RFID system typically consists of a tag and a reader.

Developed in 1973 by the Frenchman Roland Marino, the smart card was not introduced commercially until 1981, when the French state telephone system adopted it as an integral part of its phonecard network. This led to widespread use in France and then Germany, where patients have health records stored on the cards. A large-scale pilot program involving 40,000 people and 1,000 retail merchants and using smart cards as stored value, or electronic purse, cards—in which the card contains a stored monetary value that is decremented with each purchase and incremented by loading additional value onto the card through automated teller machinesautomated teller machine

Smaller pilots were held in Canberra, Australia; in the Atlanta, Ga., metropolitan area in conjunction with the 1996 Summer Olympic Games; in New York City; and in Guelph, Ontario. All of these achieved only limited customer acceptance and were shut down by 1998. Another major problem is that these and other smart card ventures did not have a common technology. The development of the EMV standards for credit and debit cards in the 1990s, and the subsequent widespread adoption of these standards has led to global acceptability, but the United States did not see widespread adoption of the technology until 2015. The EMV chip is used with a signature or personal identification number (PIN), with the preference for signature or PIN varying by country; many EMV smart cards also have a magnetic strip for backward compatibility.
As memory capacity, computing power, and data encryption capabilities of the microprocessor increase, smart cards are envisioned as replacing such commonplace items as cash, airline and theater tickets, credit and debit cards, toll tokens, medical records, and keys. Suggested government use of a single smart card to replace driver's licenses, passports, social security, welfare, and health documentation, and the like has caused a debate concerning the civil liberty implications of such uses of the smart card, but cards with some or many of these capabilities have been adopted in a number of countries.
smart card[′smärt ‚kärd]
Smart cards are being incorporated into soldier's dog-tags and used to store hospital patients' medical records. This way they are always instantly accessible.
Other uses are as a form of token in banking systems. You could store electronic money on the card or less valuable tokens such as those given away by petrol companies which you collect to exchange for free gifts at a later date. The idea being that one smart card is easier to carry around than a multitude of paper tokens.
smart cardA credit card or ID card that contains a chip. When inserted into a reader (contact card) or held within a few inches of the reader (contactless), data are transferred to a central computer. Also called a "chip card," smart credit and debit cards adhere to the Europay, MasterCard, Visa standard (see EMV). Smart cards can also be programmed to self-destruct if the wrong password is entered too many times. As a financial transaction card, it can be loaded with digital money.
Contactless Smart Cards Are Like Passive RFID
Like an RFID tag used to track merchandise and vehicles, a contactless smart card is also energized by receiving a radio frequency (RF) transmitted over the air. However, the smart card uses a microcontroller that can provide authentication, encryption and financial processing, whereas RFID tags generally contain only identification data. See EMV, NFC, magnetic stripe, PIV, SIM card, RFID, Java Card and FeliCa.
