About Smart Card Chips
Smart card chips contain a microprocessor and/or memory. They are embedded in smart cards; portable devices that resemble credit cards but are used in applications such as banking and health care. Although the term “smart card” is used to describe any card that can relate information to an application, passive devices such as magnetic stripe cards, optical cards, and memory cards can only store information or complete pre-defined operations. By contrast, smart cards with embedded microprocessors contain all of the information and functions needed to complete transactions. Known as “chip cards”, these microprocessor-based devices do not require access to remote databases and can perform a dynamic series of complex calculations. Although smart card chips that include both a microprocessor and memory offer the greatest degree of versatility, the majority of smart cards are memory-only devices.
There are three basic types of smart card chips. Contact chips are read by an independent card reader and conform to ISO 7816, the International Standards Organization (ISO) specification for the standardization of smart card systems. Contactless chips are read by radio frequency (RF) signals instead of a card reader. They conform to ISO 14443A and include a magnetic loop antenna that operates at 13.56 MHz. Combi cards are plastic smart cards with a central processing unit (CPU), chip operating system (COS), security module and embedded memory. They incorporate both contact and contactless functions.
