Smart Cards

A smart card, chip card, or integrated circuit card (ICC) is any pocket-sized card with embedded integrated circuits. Smart cards can provide identification, authentication, data storage and application processing. Smart cards may provide strong security authentication for single sign-on (SSO) within large organizations.

The microprocessor on the smart card is there for security. The host computer and card reader actually "talk" to the microprocessor. The microprocessor enforces access to the data on the card. If the host computer read and wrote the smart card's random access memory (RAM), it would be no different than a diskette.

Smart cards may have up to 8 kilobytes of RAM, 346 kilobytes of ROM, 256 kilobytes of programmable ROM and a 16-bit microprocessor. The smart card uses a serial interface and receives its power from external sources like a card reader. The processor uses a limited instruction set for applications such as cryptography.

Contactless smart cards do not require physical contact between a card and reader. They are becoming more popular for payment and ticketing. Typical uses include mass transit and motorway tolls. Visa and MasterCard implemented a version deployed in 2004-2006 in the U.S. Most contactless fare collection systems are incompatible, though the MIFARE Standard card from NXP Semiconductors has a considerable market share in the US and Europe.

Smart cards are also being introduced for identification and entitlement by regional, national, and international organizations. These uses include citizen cards, driver's licenses, and patient cards.

A Smart Card contains more information than a magnetic stripe card and it can be programmed for different applications. Some cards can contain programming and data to support multiple applications and some can be updated to add new applications after they are issued. Smart cards can be designed to be inserted into a slot and read by a special reader or to be read at a distance, such as at a toll booth. Cards can be disposable (as at a trade- show) or reloadable (for most applications). An industry standard interface between programming and PC hardware in a smart card has been defined by the PC/SC Working Group. Another standard is called OpenCard. There are two leading smart card operating systems: JavaCard.

The most common Smart Card applications are

  • Credit Cards
  • Electronic Cash
  • Computer Security Systems
  • Wireless Communication
  • Loyalty Systems (like frequent flyer points)
  • Banking
  • Satellite TV
  • Government Identification
