- Complete Wallet Protection — Protects contactless credit/debit cards, ATM cards, ID cards, passports, and driver’s licenses without replacing your wallet.
- Universal Fit — Designed for all standard-size cards and operates on the common 13.56 MHz RFID/NFC frequency.
- Slim & Durable — Ultra-thin metal construction fits seamlessly in wallets and purses; waterproof and easy to clean for everyday use.
- 4-Pack Value — Keep one in each wallet, purse, travel document holder, or share with family and friends.
How It Works
Unlike passive sleeves that block signals by shielding, this card actively interferes with the electromagnetic communication between a reader and your contactless cards. When placed in your wallet, it generates a jamming signal that disrupts RFID/NFC scanning within a short radius, preventing unauthorized devices from reading your card data.
Practical note: The effective disruption radius is approximately 2.4 inches (total), which is sufficient to protect cards placed next to the blocker. For best results, place the blocker in the same stack or adjacent slot as the cards you want to protect.

Frequently Asked Questions
- Will this card work with all contactless cards?
- Yes — it is designed to protect standard 13.56 MHz contactless cards, including most credit/debit cards, IDs, and e-passports.
- Does it damage my cards or block legitimate transactions?
