Smart Card Definition

A smart card is a small plastic card-usually a credit card-featuring an embedded integrated circuit capable of processing and exchanging information. The use of smart cards varies tremendously and there are several kinds in common use-some receive and store information, others transmit information, and still others are capable of rudimentary processing. Most consumer smart cards are a form of credit card that combines benefits of a credit card and a debit card. Smart card technology rapidly is evolving and new features are constantly added.
