Do you think that it's still worth it to buy a wallet or case that has RIFD protection to put your bank cards in or is that technology outdated?

I bought a couple of card holders and a wallet when RIFD protection first came out.
But now I am seeing criminals can just walk by you and get your banking information by using some kind of scan.
