Transonic® RFID/NFC Blocking Card | Contactless Cards Protection | 1 Card Protects Your Entire Wallet.

Our advanced technology blocking card draw energy from any present RFID scanner, which means they need no charging, or batteries to work! Our RFID blocking card offers 100% protection for bank cards and passports only, because they all operate in a frequency of 13.56 Mhz. Most institutional access cards and devices operate on other frequencies, so our RFID card cannot protect them. Simply place a single Transonic RFID blocking card in your wallet or purse and you're protected. No fiddling about with individual sleeves. No need to fork out for a new wallet or purse. You can carry on using your contactless cards as normal. Simple and effective. You can test our Signal Blocker yourself by placing it on top/ underneath of your credit/ debit card when trying to complete payment at a self checkout. Our blocking card will instantly prevent any payment from being processed. Because the Transonic card draws power from radio waves, it doesn't contain a battery. Please note it is slightly thicker than a standard credit card due to the internal circuit, 1.2mm thick instead of 0.76mm (barely noticable). The Transonic 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. The Transonic card contains an antenna and chip. When radio waves from an incoming scan pass through your wallet, the Transonic card draws power from the waves and creates a jamming signal. All cards surrounding the Transonic card within a 2.5cm radius will be protected.
