At first glance, the blocking sleeves aren't too impressive. They're basically thin tyvek envelopes with metallic coatings on the inside. Honestly, at first glance they appear a bit flimsy and don't look like they would stand up to a lot of use, but the credit card sleeves are identical (except for color) to the one that the bank sent my credit card in, and I've been using it for several years, and it's still in good shape. If you're not familiar with it, tyvek is virtually indestructible. You can cut it with scissors, but it's very difficult to tear it or puncture it.

A few years ago, the U.S. General Services Administration (GSA) issued a set of test procedures for evaluating electromagnetically opaque sleeves. For shielding products to be in compliance with their FIPS-201 guidelines, they must meet or exceed this published standard. Shielding products currently evaluated as FIPS-201 compliant are listed on the website of the U.S. CIO’s FIPS-201 Evaluation Program. I checked the current list, and Identity Stronghold shielding sleeves are shown as compliant with the standards with no restrictions. That's proof enough for me.

The Identity Stronghold RFID blocking sleeves are a well made, effective product that meets the established standards for shielding credit cards, passports, and other types of contactless identity cards.

They arrived promptly, and they are exactly as described.
Got them for travel, but they are my every day cardholders now. I put stickers on them and use clear packing tape to keep the stickers on to beef them a bit. As pulling the cards in and out often will quickly wear them out.
The stickers are a quick easy way to identify what credit card is in which sleeve.

We used these on our recent trip to Europe. We know these credit card and passport sleeves worked since security stopped us - their scanners couldn't penetrate. They are just paper on the outside and, once used for awhile, became flimsy. Was not easy to put cards in and of them. Next trip, I think I would buy an actual RFID wallet or case.

I'm lucky that my passport was issued before they implemented the new RFID Passports, however come renewal, I'll end up getting one and this passport RFID blocker will come in really handy. I have a few cards that have chips in them, a few AMEX's and a debit card or two. I've never been virtually pickpocketed but now I feel much more secure.

My office uses a RFID in my badge and I tested a few of these holders at the entrance. I'd swipe my card by the reader, then changed the sleeve to a different one (you get 10 credit card sleeves total). I tested all 10 and they worked without fail, my card wasn't even recognized until I took it out of the sleeve, I'm a believer now.

These envelopes are designed for credit cards that support RFID and passports. RFID allows you to not to swipe the card when doing purchases. How can you tell if you credit card supports RFID? RFID cards display a PayPass logo, which looks like waves (my video includes a couple of examples).

I got this for travel, but have been using one of the small envelopes for one credit card that supports RFID for over a week and so the card sleeve is holding up fine.

This is a very simple product: a thin Tyvek envelope with silver lining which creates electromagnetic shield. These sleeves follows FIPS 201 standard. This standard was established by US government for protecting information stored on the card against skimming attacks.

This set includes five credit card sleeves and one passport holder. I like that they are thin and look very similar to the Tyvek envelopes that my banks used to provide (but without the electromagnetic shield).

These sleeves are provided by "Number 1 in service".

I have RFID readers on all the doors where I work and they really do block any signal. I think you could put one on each side of your cards if you keep them all together in your wallet and not have to fight getting them in and out of the pocket of the sleeves all the time. The edges get deformed on the end where the card slides in and sometimes it takes a little effort to get the card back in the sleeve.

Although we haven't been subject to any "security" theft it may be because the credit Card & Passport holder Guards are working.

this worked well for my overseas travel and I now use them all the time. I just put a notation on each sleeve so I'll know what's inside. Love knowing that my info can't be hacked while in my purse

I had total confidence that my critical documents were safe in any and all situations while traveling.
I'll never know if they worked or not...and I hops I never do.
