smart card - Computer Definition
A credit card–sized device (or sometimes smaller) that has a embedded computer chip. This chip not only provides storage functionality but also can run programs. Smart cards are used in a number of security-sensitive applications. One important application of Smart Cards is in wireless telecommunication, where Smart Cards are used as Subscriber Identification Modules (SIM).
Another use is the health insurance card now employed in several countries around the world. The patient card contains a patient’s health history and a record of previous prescriptions. In addition to this data, a number of security algorithms are implemented on the card so that only properly authorized parties—doctors and/or nurses—can access and alter this data when they successfully establish their identity and authentication through the usage of a health professional’s version of the card.
A business card-sized card containing a chip and storage that is used for identification or financial transactions. When inserted into a reader (contact card) or via wireless NFC (contactless card), the card transfers data to a central computer and receives responses. A smart card is more secure than a magnetic stripe card and can 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. See EMV, NFC, magnetic stripe, PIV, SIM card and Java Card.
