SaiTech IT 5 Pack RFID Blocking Card, One Card Protects Entire Wallet Purse, NFC Contactless Bank Debit Credit Card Protector ID ATM Guard Card Blocker–(Black)

This is truly 1 product you do not want to fail... From what I can see, it seems to work as intended, but the problem seems with this type of product... is that you may never know if it is really working or when it stops working... At least until you hear that your Credit Card(s) were hacked and I have had that happen before. At this time, I see this Item as a needed item in my wallet for Protection from Thieves. They seem to be just as Durable as a Credit Card, Seems to offer security and protection, and I will try to follow up on that later... Color is Black with Gold print and logo. Not sure why they offer Capacity as an item to review... But for the 4 cards that I want protected... I would say it is good... Now days... any protection is a good think!

Seems to be working as it should. I received it a few weeks before Christmas and went to very, very busy stores over the holidays and have had no issues far. Love the size and the fit in my wallet. Great value for the money paid.

Worked great, I test this while trying to buy something, i had the blocker card inbetween my debit and the POS machine and then again with the blocker behind my debit and the POS machine and both times the machine could not recognize my card until i put the blocker in my back pocket and then scanned my debit successfully. I would say it works as intended. i will leave 1 in my wallet from now on and 1 in my girls wallet. Thank you

It's up to the test. In theory, it's a preventive gadget. Time will tell its efficiency. I hope it does its job.

Each card is roughly the same standard size as a typical credit or debit card, so they fit neatly into a slot in any wallet with cardholders. They are inexpensive, easy to position, and require no additional steps. I also appreciate the fact that they look fairly sleek and official, though function is obviously more important than appearances. I've yet to test them at a register to ensure they actually interfere with machines reading cards or NFC on my phone, but I will be doing that the next time I am in a position to do so. For now, they're simply something to provide a little more peace of mind for me when out and about.

Be careful about sellers distributing the same product as one or two units. The cost is often double the price of this entire set of 20. I used this next to the scanner with my bank card, and the unit was unable to register my card. Placed the card back in my wallet, and the scanner correctly registered my bank card data. IT WORKED PERFECTLY.

We got this for peace of mind. The blocking cards protects drivers licenses and credit cards. As you can see in the photo, it's the same size and thickness as a standard credit card and just one card protects your entire wallet. Just to be safe, we use two blocking cards in our wallet. When you want to tap and pay, make sure the blocking cards are three to five inches away from the credit card you are using. The blocking cards do not require batteries and never need to be charged to provide a lifetime of peace of mind. You can't beat the price - 5 blocking cards for under $10. One last thing: It's better to prevent a problem from occurring - than trying to clean up the mess. We never leave home without these. Five out of five stars!

Great product

ok

Used it at a friendly store to Tap and Pay, in various shielding positions. It works.

To my knowledge they work extremely well

La probé y funcionó el bloqueo. Lo extraño es que, momentos después de la prueba, la terminal no pudo leer mi tarjeta ni siquiera tecleando el nip. Al día siguiente fui a mi sucursal bancaria a solucionar el tema pero para mi sorpresa ya funcionaba perfectamente. Así que, probablemente la bloquea por cierto tiempo.

It does the Job as a shield against scanning devices.
