When RFID (the chips in credit cards that send out a signal) first starting showing up there was a lot of talk about skimmers being used to snag info from your credit cards in your purse or wallet without you even knowing that someone had stolen that info. But a simple solution to protect your cards' info was to wrap them in tin foil.
Yeah, that's not realistic, is it? Besides looking rather, let's say, horrendous, unpeeling tinfoil from your credit card every time you want to use it isn't really logistically sensible. I decided to try to combine a wallet/card holder with tin foil. That did not work well. At all. In fact, it was quite a disaster.
Besides the tinfoil not wanting to cooperate when turning a sewn fabric wallet inside out... well, that was the stopper actually. After forcing it the tinfoil was so destroyed that the crumply mess was beside the point.
I decided recently to re-visit the RFID tinfoil card holder idea because of the sudden resurgence of cards with RFID chips embedded in them due to the need of credit card companies to have them now, not just an option.
I wracked my brain and wracked my brain for a solution which did not require forcing the tinfoil to be sewn into a wallet/card holder and forced to be turned inside out with the surrounding fabric. I have found a solution!!
There are quite a few discussions on whether tinfoil will even work to block the RFID signal but I have seen reliable articles saying that tinfoil does the trick, as long as it's at least .27mm thick. That's extra heavy duty Reynolds wrap.
So, experimenting begins! When I have the finished product I will post instructions and you can decide if you want to add a little touch of RFID insulation and protection to a card holder that will definitely be more appealing in functionality and aesthetics than simply wrapping your cards in tinfoil but with the same protection against skimmers.
Hint: The little remote shutter release pocket was what gave me the re-inspiration to give RFID protection another try.
