Benefits of Contact Smart Cards
Contact smart cards must be ｉｎｓｅｒｔed into a smart card reader. The reader makes contact with the card module electrical connectors that transfer data to and from the chip. This physical contact permits the transmission of data, commands and card status and enhances security by requiring the card holder to be present for identification.
Advantages of Contactless Smart Cards
Contactless smart cards are embedded with an integrated circuit chip. They provide not only memory capacity, but computational capability as well. The self-containment of a contactless smart card makes it resistant to attack as it does not need to depend upon potentially vulnerable external resources. Because of this characteristic, smart cards are often used in different applications which require strong security protection and authentication.
RFID Smart Card
Radio frequency identification (RFID) is a generic term that is used to describe a system that transmits the identity (in the form of a unique serial number) of an object or person wirelessly, using radio waves. A RFID system consists of an antenna and a transceiver, which read the radio frequency and transfer the information to a processing device, and a transponder, or tag, which is an integrated circuit on the plastic smart card containing the radio frequency circuitry and information to be transmitted.
