Saw that a couple of weeks ago on a site selling wallets with aluminium sheets in them which they say stops them being scanned
See bottom of page:
Secure Wallet -
A few months ago I watched a documentary where a man was walking through an airport terminal with what looked like a laptop getting peoples bank details by walking near them with this device. It was a $12 scanner and all he had to do was pass this devise near some one and he had their details.
These new quick cards are designed so you don’t have to sign or put in pin numbers etc. You just wave it over a scanner and walk away. Sounds great doesn’t it? How convenient.
On this show the Banks defended the new card by saying, “ The cards are only good for small goods up to $100 per day.” When asked about accessing someone’s personal information, They said “Just wrap the card in Aluminum foil to stop the signal.” I don’t know about you, but in my eyes, there goes the convenience out the window.
Our secure wallets have two .05mm aluminum plates sewn into them. One in the front and one in the back to sandwich your cards. We’ve tested them and they work.
Flexible enough so it doesn’t feel like you have a deck of cards in your back pocket but strong enough to last for years. You can’t see the difference, but you’ll feel secure knowing it’s there.
