what do people use to block RFID in Wallets?

[ToddW]

I see these wallets that say they block RFID readers.. what do they use to do that?  is it a liner?

For my own personal credit card, I went to the bank and got the ' pay wave' component deactivated .  The EFTPOS machines kept picking up my credit card while it was still in my wallet and no-where near the machine, it was in my left hand and I do transactions with my right, either with cash or a savings card, go figure.  I didn't realise how sensitive those machines are.

But I really should think about using RFID shielding  when I make wallets.

I use plumbers' aluminium tape. A roll of about 45mm x 45m costs, generally, under £/$5, Wider widths and longer rolls are available but I find 45mm wide suitable.  I've tested it and it works well, it blocks even sensitive card readers from reading cards right up to touching them. And a roll will last you a lot of card holders or wallets. Its very thin and self-adhesive. Just stick it on one or both pieces of leather forming the card pocket and cover with a thin piece of cloth lining material

As fredk recommends, aluminum foil works great too! Most gimick fabics dont work from my experience(ex IT geek), lots of theives line thier bags with alfoil to evade scanner...

Im keen to make a rfid card holder too but looking for alternatives to aluminum, would that work long term? Also it has to seal well or be wrapped to work well?

I use a scalpel and cutt the antenna off the chip, hold your card upto a bright light and make two cuts on each side off chip. Chip still works! Never trust a bank, lol.

The aluminium tape works, why look for an alternative? Why should it not work long term? There is no 'wear & tear' on its blocking

I made a simple card case as tester. The case held four cards. I put a piece of the adhesive aluminium tape on the inside side of each outer cover. Each piece was slightly larger than the cards.  I covered that with thin cloth and sewed it up. No card reader could read any of the cards in the case.

I like the KISS solution. Cheap, simple, effective and functional.

I was only concerned with long livity, most alfoil and tape seems to 'tarnish' and deteriorate over time. In usa it might be better than the junk were sold down under, lol
