Stealth Shield RFID Blocking Card (2 Pack) - Maximum Strength RF/NFC Blocker Device for Bank Credit Card & Identity Protection - Wallet Security Against Illegal Contactless Credit Card Scanning
- HOW DOES IT WORK? - The Stealth Shield RFID card contains an antenna and chip. When radio waves from an incoming scan pass through your wallet, the card draws power from the waves and creates a jamming signal. Any cards either side of the Stealth Shield card within a 2.5cm radius will be protected.
- MAXIMUM PROTECTION FOR YOUR CONTACTLESS CARDS - Simply place this Stealth Shield RFID blocking card in your wallet or purse and you'll be secure and protected.
- NO BATTERIES REQUIRED - This Stealth Shield card draws power from radio waves so batteries are not required. Please note it is slightly thicker than a standard credit card due to the internal circuit, 1.2mm thick instead of 0.76mm. The Stealth Shield RFID blocking card doesn't affect phone signal, bluetooth, WiFi, or any of your other phone functionalities (except NFC) so you can use it in a phone card case without issues.
