Skamz Car Mobile Card key Signal Blocking Pouch Guard your vehicle against technology-smart car thieves with this superb value pack of two large signal-blocking key fob pouches from us. These safety-focused mini-bags feature an outer PU leather casing, containing a metal-lined soft sleeve. This creates a Faraday box, stopping signals being sent or received by your key fob or any other device containing data. Remove your key from the wallet and signal reception is restored immediately, enabling normal usage. These covers also include a further, non-lined compartment; handy for storing your house keys or loose change for the parking machine! Anti-Theft Protection : Modern keyless fobs carry identification chips that pick up radio signals sent out by their car. The vehicle recognises the fob when it’s in range and unlocks the doors. Keyless ignition systems work in the same way – enabling cars to start when the key fob is detected in the cabin. Criminals can exploit this via a wireless relay attack. Using a radio frequency relay booster, it’s possible to pick up and then transmit a keyfob signal to trick the car into thinking a fob is present. This enables entry and theft from the cabin or boot – and, in the case of keyless ignition systems, theft of the vehicle itself. Thanks to its 100% signal jamming capability, this protective holder completely isolates your fob to make such attacks impossible – giving you complete peace of mind as a protector against data loss. Data Protection and Privacy, Cloning and Fraud Prevention: As well as keyfobs, these versatile anti-degaussing cases can be used to shield all manner of smaller items that contain or transmit data and code, from ID tags through to contactless cards. It makes these pouches one of the best ways to add a big layer of defence against ID theft, hacking and fraud.
