Take Control of Your Security and Stop Worrying About Digital Theft
Deffenda gave our customer peace of mind and changed the way they protect their money and identity. You can protect yourself too!
James
I really used to think digital pickpocketing was just fear-mongering. Then one day, I noticed an unauthorized charge on my credit card after going to Italy. My wallet wasn’t stollen or anything but some of my money was gone!
That’s why I decided to get Deffenda. Now I feel much better knowing that nothing like that will ever happen again.
Kenneth
I had an RFID-blocking wallet thinking it was the best option, but honestly it was too bulky and annoying to carry. Especially since I like keeping my wallet in my pocket. A friend showed me Deffenda and it’s much better. I just have it my regular wallet at all times and don’t think about it twice. It’s nice not having to fiddle with a hefty wallet twice the size of your fist.
Patricia
I’ve always worried about digital theft, especially in airports and busy cities since I travel regularly for work. It’s embarrassing, but I even used to wrap my credit cards in aluminum foil because I didn’t trust other RFID protectors. Getting Deffenda was a much better option! It fits so nicely in my wallet and it protects all my cards at once!
Why Deffenda is the Smarter Choice
No Other Protector Comes Close
RFID-blocking sleeves and wallets can offer some protection but often only work for one card at a time and wear out over time. Deffenda shields your entire wallet instantly, lasts for years, and requires no extra effort.

No more paranoia
I never realized how easy it was for scammers to skim my credit card without even touching my wallet. Thank God a friend told me about RFID theft, and I immediately got Deffenda. Now, I feel way more secure when I’m out shopping or on public transport. One less thing to stress about!

Should have gotten something like this sooner
Last year, someone stole my credit card info without me even realizing it. The bank refunded me, but it was a nightmare to deal with. I just can’t go through that again, so I got Deffenda. Only wish I did it sooner..

Good fix for such a big problem!
Realized I’d been using contactless cards for years without any protection after reading an article about it! Ordered an Deffenda right after and now I feel so much safer. It’s such a simple fix for such a serious problem!

“Deffenda was rated as the best RFID-Blocking Card of 2025”
- TopRatings.Review
Meet Our Expert,
Cybersecurity & Identity Protection Specialist
Most people don’t think twice about tapping their credit cards to pay. But what they don’t realize is that the same contactless technology can be exploited by thieves. With the right RFID scanner, someone can skim your card details from several feet away without you ever knowing. I’ve tested dozens of RFID-blocking solutions, and many don’t work as well as they claim. Deffenda is different. It instantly disrupts RFID signals, making your cards invisible to skimmers. It’s slim, requires no charging, and works 24/7 without any effort. If you carry contactless cards, this is the easiest way to protect yourself.

Frequently Asked Questions
How does Deffenda protect my cards?
Deffenda uses advanced RFID-blocking technology to create a 5cm electronic shield around your cards. This instantly blocks skimmers and unauthorized RFID/NFC scans, keeping your credit cards, IDs, and passports safe in crowded places like airports, malls, and public transport.
Do I really need an RFID-blocking card?
If you carry contactless credit/debit cards, smart passports, or RFID-enabled IDs, your data can be wirelessly skimmed without you ever realizing it. Deffenda prevents digital theft before it happens, giving you peace of mind wherever you go.
Will Deffenda interfere with my cards?
No, Deffenda only blocks unauthorized scans. Your tap-to-pay, ATM withdrawals, and card readers still work as usual once you take the needed card out of the wallet.
How do I know if my cards have RFID technology?
Look for a Wi-Fi-like symbol on your card – that’s the sign of RFID technology. Most contactless cards use RFID, but if you’re unsure, you can check with your bank or card issuer.
How does Deffenda differ from RFID-blocking wallets or sleeves?
Unlike bulky RFID wallets or flimsy sleeves that require each card to be placed separately, Deffenda protects your entire wallet at once.
How long does Deffenda last?
Deffenda is built to last for years. It’s waterproof, tear-proof, and highly durable, so you never need to replace it. Unlike RFID wallets or sleeves that wear out over time, this one card provides ongoing protection without maintenance.
Does Deffenda block all types of RFID scanning?
Yes, Deffenda blocks all high-frequency RFID and NFC signals. It ensures your credit cards, passports, and IDs remain invisible to digital thieves.
