There is a company out there that developed a product which looks like a simple card ( format of a credit card or so ) and claims to block rfid-signals in a distance of 10mm. It is not a case to protect a card but rather card which you put over the card/cards you want to protect. Is this actually possible or is that a fraud?

I am not talking about two cards blocking rfid signals like in this example but one card that can block anything in a distance of 10mm. Is this possible and if it is can you provide me a trusted source for this?
