Schembo 16 RFID Blocking Sleeves Set (12 Colorful Credit Card Protector RFID Blocking Sleeve & 4 RFID Passport Holder). Effectively Protect Your Credit, Debit, and ID Cards From Electronic Theft.

works very well. in some stores I have to swipe my card to get in. I have tried to swipe it while in the sleeve and it blocks it from reading. have had the sleeve for six months and after much use in my wallet they are still in good condition. all my cards fit snugly in the sleeves so they will not fall out by accident. good value for the price. Am well pleased with them.

Excellent product. There was a review on TV of all the different RFID blocking products on the market which included many expensive alternatives. I tried these because they were found to be the best thing you could use an amazing price. They are very attractive in their appearance as you pull them out, they have been durable, and I find them assuring me that my credit cards cannot be utilized. If you like to keep your credit cards in slots in your wallet the thickness of these will probably make that a little more difficult, but the convenience of not having your credit card compromised is well worth the purchase.

.....go ahead and say I've "too much time on my hands" but ?? I am a fast typist so it's not that bad. I ...rushed... yes, and I "DO HAVE 'a life'" to write a review of these. ESPECIALLY if you have an around-the-waist MONEY BELT...from Amazon...one of those 3" x 4,5,6" with elastic belt ???? ...often you're in a PUBLIC place exposing your money belt AND having to rifle through cards to be sure you're pulling out the RIGHT CARD ???? The COLOR CODING helps tremendously. .....Green for favorite MONEY card.......blue for navy related, etc. AND of course while protecting the card RFID-wise WHILE making it easier and faster to pull out the RIGHT CARD... ALSO A PLEASANT SURPRISE: the FOUR (4) sized ones for your PASSPORT !! 'can't beat it especially for the price. Might buy another set for more variety / number of colors.

Very lightweight and easy to carry around. They don’t take up much space and make it simple to keep cards organized and protected. The different colors also help with quick identification.

These are credit card blocking envelopes to prevent your cards from being scanned without your knowledge. The number of bad people in the world seems to be increasing so this is a tool against electronic theft of your credit card. If you don't want to wrap your cards in aluminum foil try these. They work well and credit cards fit easily into the envelope.

these worked perfect while in Japan. every card fit and the convenience was great.

Love these!! I a small card and ID holder and love how I tell what card is what by the color I put it in. Makes it som easier for me to find a card or ID quickly. Hopefully the blocker is doing its job by protecting my cards from hackers. I hope to never have to find out.

Very well made ..I wish they were a bit longer and had a hole in one corner to put a ring thru to keep together à they r slippery in wallet....they don t fit normal size card slots in wallet...
