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!

Great product

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.

I bought these RFID-blocking cards to protect my credit cards from electronic pickpocketing. While I haven't had any security issues since using them, there's no clear way to test if they're actually working—which leaves me cautiously optimistic rather than completely confident. Pros: - Slim & Convenient: Fits easily in any wallet slot without adding bulk. - Affordable Protection: Cheap insurance against potential RFID skimming. - Multi-Pack: Comes with multiple cards, so I can spread them between different wallets. Cons: - No Way to Test Effectiveness: Unlike Faraday bags (which you can test with your car key fob), these can't be easily verified. - Uncertain Longevity: No indicator when/if the shielding wears out over time. Experience: I’ve carried one in my wallet for months alongside my contactless cards. While I haven’t experienced any unauthorized scans, I also can’t definitively say whether that’s because of the blocker or just luck. It doesn’t interfere with my wallet’s functionality, though. Comparison: Unlike thicker RFID-blocking wallets, this doesn’t add bulk—but it also only protects cards placed directly next to it. A full shielded wallet might be more reliable for complete coverage. Tips: - Place it closest to your most sensitive cards (like credit cards or ID). - If you’re truly concerned, pair it with a Faraday pouch for high-risk situations (like traveling). Final Thoughts: For the price, it’s a reasonable "better safe than sorry" purchase. But if you want guaranteed protection, you might want a more verifiable solution like a shielded wallet. It does its job invisibly—I just wish there was a way to confirm it.

These work. I tried and tested these before I left on my trip and they work. My card would not work when this card was near it. I now have one in my purse, backpack, luggage and other bags. I definitely recommend this product and I feel a little safer. Especially in the airport.

Purchased these and handed them out to family members. I have tried to tap my CC on the machine with the RFID card on top or bottom of my CC and it won't read it until I remove the RFID card. That proves to me it is scrambling the data and not allowing my card to be read!! I believe we have a winner here folks!!

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!

ok

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.

Actually works. As a check point Tap and pay dosent work when this card is placed below your card. While the technology works, many experts note that RFID skimming is actually quite rare in the real world. Modern cards use encryption that makes it very difficult for a thief to do anything useful with the limited data they might manage to skim.

It does the Job as a shield against scanning devices.
