Smart Card Description

A SIM card is basically a Smart Card used to store the identifying key for a mobile phone. Smart Card defines the physical and electrical protocols for a plastic 'chip card' used to store data. A Smart Card can hold much more data then via a simple magnetic strip. A Smart card will either have an embedded memory chip to store data, or an embedded microprocessor to interact during a transaction. Smart Card uses normal TTL switching levels. Smart Card come in two different interface types; a contact type and a contactless type. The contact-less type uses an embedded antenna. The contact type has an 8-pin flat connector embedded on the top of the card.

Smart Cards are also referred to by other names depending upon its application:
UICC Card [Universal Integrated Circuit Card], Smart Card used in mobile phones.
SIM Card [Subscriber Identity Module], the type of application running on a UICC Smart Card.
