Don’t let nefarious government agencies and rogue nations track your comings and goings just because you don’t have a pocket for your RFID-proof wallet. For a limited time, I’ll be selling replicas of my revolutionary RFID-Buster Flip Flops. These sporty flips feature discrete pouches (one in each) that hold your IDs, credit cards, and even cash. The upper is fully encased with space-age material, which completely blocks the radio-frequency queries from nearby transceivers.
