'On' and 'Off' switch design to avoid credit card RFID and NFC theft

Gone are the days of heavy wallets, just a couple of cards work fine for the new web-age. Using near-field communication (NFC) and radio frequency identification (RFID) further negates the need to swipe credit cards through an interrogative machine. One has to simply wave the card and the money will be withdrawn from the bank account and the purchases will be made with ease. However, this method could be susceptible to fraud and theft. To avoid this, researchers at Pittsburg Swanson School of Engineering have built an improved method for enhanced security through new credit card design that allows it to turn ‘on’ and ‘off.’ Click here for full story
