F.A.Q
Technology & How It Works
A Faraday cage is an enclosure made of conductive material that completely shields electromagnetic fields. English scientist Michael Faraday proved this in 1836: he built a room lined with metal foil and discharged high voltages on the outer wall. Using an electroscope, he demonstrated that no electrical charge was measurable inside.
TOCA products use this principle — the special metal mesh blocks all signals transmitted into or out of the pouch.
No. In airplane mode your device doesn't actively transmit data — but it still receives. You can still be tracked via GPS, for example. Only complete physical shielding (the Faraday principle) prevents both transmitting and receiving entirely.
No. Even a switched-off phone can send and receive data. Edward Snowden explained in a BBC interview the NSA technology "Dreamy Smurf": it can turn mobile phones on and off without the user noticing.
A TOCA bag physically blocks all signals — regardless of whether the device is on or off.
TOCA products block all common wireless signals in the frequency range 100 MHz – 6 GHz:
- Keyless entry / key fobs (315–433 MHz / 868 MHz)
- RFID & NFC (contactless cards, passport, ID card)
- GSM / LTE / 5G (mobile networks)
- WiFi (2.4 GHz & 5 GHz)
- Bluetooth
- GPS
Shielding effectiveness exceeds 99% (DEKRA certified).
Keyless Entry & Vehicle Protection
In a relay attack, two thieves work together: Thief A stands near your vehicle, Thief B approaches your key (e.g. at your front door or in a restaurant) with a signal amplifier. The amplified signal tricks the car into thinking the original key is right beside it — the car unlocks and can be started.
TOCA key pouches block the key signal completely. No signal, no relay attack.
No — and that's the whole point. As long as the key is inside the closed bag, the keyless entry signal is completely blocked. The vehicle cannot be opened or started.
To open your vehicle, simply take the key out of the bag. This takes about 2–3 seconds — your conscious, active security moment.
For all vehicles with a keyless entry system. Keyless entry operates on similar frequencies across all manufacturers (315–433 MHz / 868 MHz). TOCA products cover 100 MHz – 6 GHz — this includes all systems, including:
- BMW, Mercedes-Benz, Audi, Volkswagen, Porsche
- Tesla, Toyota, Honda, Hyundai, Kia
- Ford, Vauxhall, Renault, Peugeot, and more
Products & Compatibility
Almost certainly yes. The pouch fits devices up to 165 mm × 82 mm. The following devices are too large:
- Samsung Galaxy Tab A 7.0
- Huawei Honor Note 8
- Sony Xperia Z Ultra / Sony Tablet P 3G
- LG Optimus L3 E400
- HTC Nexus 9
- Samsung Galaxy C9 Pro
All other common smartphones (iPhone, Samsung Galaxy S/A series, Google Pixel etc.) fit without any issues.
Our recommendation for maximum shielding:
- Enable airplane mode on the device
- Place the smartphone in the TOCA pouch
- Close the pouch completely
The device won't actively transmit data, and the pouch blocks all incoming signals. Result: complete electromagnetic isolation in both directions.
Quality & Certification
Yes. TOCA products are independently tested and certified by DEKRA Automobil GmbH (Germany). Measurements confirm shielding effectiveness of over 99% in the frequency range 100 MHz – 6 GHz — covering all relevant keyless entry, RFID, NFC, mobile, WiFi, and Bluetooth frequencies.
The shielding is based on a special metallised technical fabric (directional electromagnetic shielding). The outer shell is made from high-quality nylon or faux leather, depending on the product. Designed in Germany, manufactured to European standards.
