A CDE Definition
A small length of magnetic tape adhered to credit cards, badges, permits, passes and tokens. The tape is read by magnetic stripe readers incorporated into ATMs, identification readers and payment terminals. Due to the daily, heavy wear these cards receive, the digital recording on the stripe is in a very low-density format and often duplicated several times in case part of the stripe becomes damaged. See smart card.
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.
