RFID Blocking Cards (2 pack) by THE CARD VAULT Protect Credit and Debit Cards With RFID Chip From Identity Theft, Skimmers and Hackers

I bought these to write a blog post about scammy products and gullible consumers. I am a tech geek and ham radio guy and amused with how gullible people are, remember the Wi-Fi spray sold on eBay?I tested these with my RFID and NFC scanners and was completely shocked, they actually DO block the signals. Not only blocked the signals, but using this I could not even DETECT a signal. It wasn't shaded, or lowering the strength but my scanners showed that there was nothing even there! Great product and kudos to this manufacturer for actually putting the time and money into a real product that does what is advertised.

Compact and makes me feel secure. Not able to prove that it works as stated (Unless my info is compromised I won't be able to prove it doesn't either), but I like that you only need one for the wallet instead of one for each credit card.

I really don’t know if it works or not but nobody has gotten my card information yet.

I like this product because, unlike card sleeves, you don't have to take your card out of the sleeve, which is really handy.

I guess they work ... Haha. It does seem to make my access card hard to read at work but those are in different freqs. Then what RFID chips on bank cards use....sooooooo well it's small and easy I even have it in a minimalist wallet.

A great credit/debit card protection card that fits just nicely into a wallet, a bit thick, but it does the job well.

It is hard to say if it works well, but I did not have any problems with stolen ID's yet.

So far so good...but it is a bit thicker than a credit card. I still recommend it!
