NON contactless credit card

You can drill a hole in through the contactless circuitry/antenna to kill the contactless function. Chip'n'pin will work as normal.

I've now had to get a load of those little conductive sleeves to shield my cards.

Do they actually do anything? I've always filed them under "snake oil" in my brain. I bought one once, in the interests of research, but never got around to actually testing it, and now I've lost it.

Does a faraday cage work?


Why yes they do.


Next pointless question please ;-)

A Faraday cage only works effectively if it's earthed, and a bit of tin foil placed between an RFID transmitting and receiving aerial at close range is unlikely to have any significant attenuation effect.

Next pointless answer please ;-)

A few sheets of aluminium will block it but the sleeves are a bit hit and miss, particularly the cheap ones and some are worse than foil!

A good sleeve does block it if you really want though of course the reader only works about 5cm away so it's not much of an issue to just hold one away from the reader which would solve the OP's issue of the wrong card being read without needing to get a new card

Have you considered investing in a tinfoil hat? Think you can even get them for your cards if so inclined

I've had the issue where I went to pay by one credit card and it read another one from my wallet instead.

I've also had this problem

That’s a new one...

Maybe to you... :huh:

Just take it out of your wallet. Why tap your wallet on the reader if you have several contactless cards in it. !!!!!!

I have different cards I use for different things (one for petrol, one for groceries etc) as I find it easier to budget this way... why should I have the inconvenience of not having the card I need with me if I need to use it without planning to before I leave the house?

My debit card (which wasn't the card I wanted to pay with) was read as I opened my purse to get the correct card out, several inches away from the reader, I didn't tap it on the reader :mad:

As above, the card can be read from a few cm away, it doesn't need to be tapped on the reader in all circumstances and so if your purse was close enough it can read it. I get the card out of my wallet and that is always well away from the reader when it's tapped.

However, there are the sort of people who get to the till, have everything scanned and then finally remember they need to actually pay for goods which means they have to grab their wallet out of the handbag/trousers, get the card out to pay etc and end up with the wallet next to the reader which can cause this problem
