A CDE Definition
A credit card or ID card that contains a chip. When inserted into a reader (contact card) or held within a few inches of the reader (contactless), data are transferred to a central computer. Also called a "chip card," a smart credit or debit card is more secure than cards with a magnetic stripe, because it generates a unique one-time code for each transaction that is impossible to replicate with counterfeit cards. Smart cards can also be programmed to self-destruct if the wrong password is entered too many times. As a financial transaction card, it can be loaded with digital money.
Contactless Smart Cards Are Like Passive RFID
Like an RFID tag used to track merchandise and vehicles, a contactless smart card is also energized by receiving a radio frequency (RF) transmitted over the air. However, the smart card uses a microcontroller that can provide authentication, encryption and financial processing, whereas RFID tags generally contain only identification data. See EMV, NFC, magnetic stripe, PIV, SIM card, RFID, Java Card and FeliCa.
