Thieves may have hi-tech skimmers, but you've got a foil-wrapped pouch. See them cower.

RFID pouches

by Chris Williams |

Isn’t it wonderful that when high-tech problems emerge, they can frequently be solved by a simple solution? That idea is perfectly encapsulated by the fictitious story about the hideously expensive American space pen and the humble Soviet pencil.

With keyless car tech, there inevitably comes keyless car thefts. An increasingly common form of car theft involves criminals using relay signals that mimic those that come from key fobs to unlock and start cars. The brilliant thing is that the solution simply involves keeping your key fob in a protective Radio Frequency Identification (RFID), signal-blocking pouch or box. No signal, no keyless car theft.

How does RFID tech work?

RFID pouches and Faraday bags work by incorporating certain materials such as copper or aluminium foil into the bag or pouch. A layer of aluminium foil, for example, blocks all signals to wireless devices being kept inside them – phone networks, 5G, Wi-Fi, GPS, Bluetooth, everything.

Consequently, key fobs and other devices are kept safe inside and no relay signal can be produced. It sounds a bit Prepper-ish and conjures images of idiots wrapped in tin foil, building home bunkers beneath their geraniums. Nevertheless, the foil trick works for signal blocking, and you can buy some quality products that tactfully hide the survivalist foil beneath a neat layer of fabric.

Our top tip in recommending the best RFID and Faraday product is not to be sucked into the ‘I’m not paying an extra £5 for one that looks the same as the cheap ones’ trick. We’ve found the super-budget ones aren’t always consistent in blocking signals, unlike those that come from established, recognized brands. If it keeps your £40,000 Lexus safe, only a fool would complain about an extra few founds.
