“It seemed to be pretty well known online that aluminum foil prevented the transmission of RFID signals. A quick test at my work place using my badge confirmed this. The next step was to design a wallet with aluminum foil embedded inside. Using the plans to make Duct Tape Wallets I created previously, it was simple to modify them to include the aluminum foil.“
And there you go.
