RFID privacy concerns getting commercialized

“What’s in your wallet?” is among the most famous advertising slogans, the implied answer being that it should be the sponsoring credit card. There’s a segment of the wallet industry that could make good use of that slogan; however, the implied answer would be that it should be the ability to block RFID. The presence of RFID chips in credit cards has added to privacy concerns about the technology and has helped give rise to RFID-blocking wallets. The irony illustrates the dilemma faced by RFID: the more it becomes mainstream the more it generates screams.
