With RFID tags in Credit Cards, Passports, and drivers licenses coming out I started to worry. Soon there will be RFID tags in money. I guess that would help solve some of the poverty problems. RFID tags are also not very secure. When the first RFID passports came out in the UK the encryption on the chips was broken in under 48 hours!
RFID blocking wallets are for sale for ~$20 (http://www.difrwear.com/products.shtml). However these are a little unstylish(yes I know its not a word) and pricey for me.
So here I will show you how to make a RFID shielded wallet that doubles as a waterproof, tear proof, cool looking ducktape wallet, without spending a fortune.
We will use Aluminum foil as a to block the radio waves that power the RFID, like a faraday cage.
Step 1: Materials
-Double sided Scotch(or similar brand) tape
