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.


History:

    The chip card was invented by German rocket scientist Helmut Gröttrup and his colleague Jürgen Dethloff in 1968; the patent was finally approved in 1982. The first mass use of the cards was for payment in French pay phones, starting in 1983 (Télécarte).

Roland Moreno actually patented his first concept of the memory card in 1974. In 1977, Michel Ugon from Honeywell Bull invented the first microprocessor smart card. In 1978, Bull patented the SPOM (Self Programmable One-chip Microcomputer) that defines the necessary architecture to auto-program the chip. Three years later, the very first "CP8" based on this patent was produced by Motorola. Today, Bull has 1200 patents related to smart cards.

The second use was with the integration of microchips into all French debit cards (Carte Bleue) completed in 1992. When paying in France with a Carte Bleue, one inserts the card into the merchant's terminal, then types the PIN, before the transaction is accepted. Only very limited transactions (such as paying small autoroute tolls) are accepted without PIN.

Smart-card-based electronic purse systems (in which value is stored on the card chip, not in an externally recorded account, so that machines accepting the card need no network connectivity) were tried throughout Europe from the mid-1990s, most notably in Germany (Geldkarte), Austria (Quick), Belgium (Proton), the Netherlands (Chipknip and Chipper), Switzerland ("Cash"), Sweden ("Cash"), Finland ("Avant"), UK ("Mondex"), Denmark ("Danmønt") and Portugal ("Porta-moedas Multibanco").

The major boom in smart card use came in the 1990s, with the introduction of the smart-card-based SIM used in GSM mobile phone equipment in Europe. With the ubiquity of mobile phones in Europe, smart cards have become very common.

The international payment brands MasterCard, Visa, and Europay agreed in 1993 to work together to develop the specifications for the use of smart cards in payment cards used as either a debit or a credit card. The first version of the EMV system was released in 1994. In 1998 a stable release of the specifications was available. EMVco, the company responsible for the long-term maintenance of the system, upgraded the specification in 2000 and most recently in 2004. The goal of EMVco is to assure the various financial institutions and retailers that the specifications retain backward compatibility with the 1998 version.

With the exception of countries such as the United States of America and Australia there has been significant progress in the deployment of EMV-compliant point of sale equipment and the issuance of debit and or credit cards adhering the EMV specifications. Typically, a country's national payment association, in coordination with MasterCard International, Visa International, American Express and JCB, develop detailed implementation plans assuring a coordinated effort by the various stakeholders involved.

The backers of EMV claim it is a paradigm shift in the way one looks at payment systems. In countries where banks do not currently offer a single card capable of supporting multiple account types, there may be merit to this statement. Though some banks in these countries are considering issuing one card that will serve as both a debit card and as a credit card, the business justification for this is still quite elusive. Within EMV a concept called Application Selection defines how the consumer selects which means of payment to employ for that purchase at the point of sale.

For the banks interested in introducing smart cards the only quantifiable benefit is the ability to forecast a significant reduction in fraud, in particular counterfeit, lost and stolen. The current level of fraud a country is experiencing, coupled with whether that country's laws assign the risk of fraud to the consumer or the bank, determines if there is a business case for the financial institutions. For example, in Australia the consumer bears the risk of credit card fraud, possibly explaining the lack of progress the banks have made in rolling out smartcards. Some critics claim that the savings are far less than the cost of implementing EMV, and thus many believe that the USA payments industry will opt to wait out the current EMV life cycle in order to implement new, contactless technology.

Smart cards with contactless interfaces are becoming increasingly popular for payment and ticketing applications such as mass transit. Visa and MasterCard have agreed to an easy-to-implement version currently being deployed (2004-2006) in the USA. Across the globe, contactless fare collection systems are being implemented to drive efficiencies in public transit. The various standards emerging are local in focus and are not compatible, though the MIFARE card from Philips has a considerable market share in the US and Europe.

Smart cards are also being introduced in personal identification and entitlement schemes at regional, national, and international levels. Citizen cards, drivers’ licenses, and patient card schemes are becoming more prevalent, and contactless smart cards are being integrated into ICAO biometric passports to enhance security for international travel.
