“SCA [defines] smart cards ... [as] integrated circuit-enabled devices which contain a microprocessor chip capable of performing calculations and communicating data to other devices, such as readers. RFID technology generally does not contain microprocessors, and more closely operates like barcodes,” said Vanderhoof. He went on to explain RFID tags store static data and communicate at a variety of speeds and radio frequency ranges. For example, the RFID technologies used in manufacturing, shipping and object-related tracking can operate over long ranges up to 25 feet. They also have minimal built-in support for security and privacy. On the other hand, RF-enabled contactless smart cards only communicate over a specific RF frequency (13.56 MHz) and range (10 cm/ 4 inches), and are designed with security features, including encryption, to increase security of the RF communications.
