Contactless Smart Cards are also known by other names such as NFC Cards (near field communication), Smart Chip Cards and Electronic Smart Cards.
In essence, a Contactless Smart Card is a storage device. Once the card is held within close proximity of a card reader (via Near Field Communication) the card is then activated. The reader can then read and write information onto the card itself. Think of it as a very small memory stick that holds information sent to it via card readers.
Some advanced cards even have processors within which act as small computers, however in most cases the cards simply act as secure storage devices.
Cards in general are used for wide variety of applications. It is therefore foreseeable that Contactless Smart Cards can be utilised across a broad range of technologies. It is the chip within the card that is the smart bit. This chip can be built into many formats (media) such as a fob, wristband, adhesive sticker, watch etc.
