(麻豆淫院Org.com) -- With technology has come ease. These days, thanks to near-field communications (NFC) and radio frequency identification (RFID), consumers no longer have to swipe credit cards through an interrogative machine鈥攖hey are able to simply wave their credit cards to make purchases or withdraw money from their bank accounts.

Such ease, however, also has brought with it theft and fraud. Researchers at the University of Pittsburgh Swanson School of Engineering have come up with a method to improve security through a new credit card design that allows a card to turn 鈥渙n鈥� and 鈥渙ff.鈥�

RFID tags and NFC credit cards are currently enabled to operate any time they鈥檙e placed in an electromagnetic field. However, that can be dangerous, says Marlin Mickle, the Nickolas A. DeCecco Professor of Engineering and executive director of the RFID Center for Excellence in the Swanson School. That鈥檚 because portable readers are now available for less than several hundred dollars, making it possible for thieves to simply pass a reader near an NFC credit card and charge purchases to it or extract cash from a bank account. 

鈥淥ur new design integrates an antenna and other electrical circuitry that can be interrupted by a simple switch, like turning off the lights in the home or office,鈥� says Mickle. 鈥淭he RFID or NFC credit card is disabled if left in a pocket or lying on a surface and unreadable by thieves using portable scanners.鈥�

With this new technology, consumers would simply hold RFID or NFC credit cards in a specified area鈥攆or example, on an emblem or some other identifying mark鈥攚hen making a transaction. As long as the 鈥渟witch鈥� is held, the card is turned 鈥渙n.鈥�  When returned to a wallet or purse and tactile contact is discontinued, the card automatically turns 鈥渙ff.鈥�

鈥淭his solution is simple and very inexpensive to integrate into the RFID and NFC credit card manufacturing process,鈥� Mickle says. 鈥淲e have filed a patent application and hope to see the technology quickly adopted, once approved.鈥�
