Your Cards Stop Answering Strangers

Your contactless card has a tiny chip. It answers any reader that comes close, even through your bag or your wallet.

How? Most smartphones now have an NFC reader built in, the same technology as a store's card terminal. With a card-reading app, a thief just holds the phone 2 to 4 cm from your bag or pocket. In about a second, your card number and expiry date can show up on the thief's screen. No touch. No sound. You feel nothing.

Guardty is designed to block remote reading of the cards next to it.

Slide it in once. Your cards stay where they are, and you pay exactly like before.

No Battery. No App. Nothing to Charge.

Here's one less thing to think about before every trip.

Guardty has no battery, no app and no settings. It works the moment it's in your wallet.

What's inside? A tiny chip. When a scanner comes close, it sends back noise. The thief gets nothing. Your card details stay yours.

No charging the night before you fly. No dead battery at the worst possible moment.

It's waterproof and tear-resistant, built to last more than 3 years.

It's Not Only Thin. It's Smart.

Guardty is the size of a bank card, so it fits in any wallet. You keep the one you love.

• Every contactless card: credit, debit, transit pass, hotel key. It protects the cards next to it.
• 1.1 mm thin: it slides in between your other cards.
• Nothing changes when you pay: take your card out and tap, like always.
• No sleeves to swap: one card does the job for the whole wallet.

What a Pickpocket Sees When He Scans Your Bag

This is not a movie scene. In 2025, police at Barcelona's Sants station arrested a man carrying an active card terminal, allegedly used to charge other passengers' cards.

What they read: your card number and expiry date. Never your PIN.

Then they use it on websites that don't ask for the security code, or sell it online.

With Guardty next to your cards, that scan is designed to come back empty.

Foil, Sleeves and RFID Wallets Ask Too Much

Every solution before Guardty worked. Each one came with a catch.

• Aluminum foil: unwrap it every time you pay, wrap it again, and it tears within a week.
• RFID sleeves: one per card, and your wallet gets so thick it barely closes.
• RFID wallets: they work, but you're stuck carrying an ugly wallet you never wanted.
• Guardty: keep your own wallet. Slide it in once and forget it. No battery. Nothing to tear. Works 24/7.
