My anti-RFID wallet

I built the wallet in the attached photograph hoping that it could block inadvertent detection of RFID chips included in more and more cards, which jeopardise our privacy in ways still unknown by most people. It consists of an empty cigarette case (which kept a delicious vanilla scent for a long time) and a simple strip of adhesive clear plastic film folded over itself like an accordion. Last weekend I checked that an RFID reader was unable to detect a card inside of the wallet. Hooray!
