An example of a contactless smart card reader is the access card for some security systems that allow an occupant to hold up a card carrying smart card technology to its reader. Even without touching, the reader will read the card information and grant the user access into the building. An example of a contact smart card is a credit card that has the smart chip implanted in its plastic. Whenever the credit card is swiped, the reader will be able to access data from the smart card. Smart card readers mainly act as a medium between a computer or a terminal to the smart card. Depending on the purpose of readers, they can be designed only as a relay of information to its main host (the computer) or to decode information and act on that information independent of a host.
