Two new products just landed. Both shield your keys and cards from unwanted signals, and both can be used for relay theft blocking and general EMF shielding.

Faraday Key Fob Pouch:

Drop your keyless entry fob inside and the shielding layer cuts its signal, so a relay attack has nothing to answer. Take the fob out and it works normally at full range.

- Blocks keyless entry relay theft

- Shields UHF, Bluetooth phone-key, and contactless card frequencies

- Two sizes: 2.75 x 5 in and 5.5 x 3 in (the larger holds a fob and a card together)

- Carbon fiber texture, keyring attached

RFID Blocking Card Sleeve

Slide your card in and the metallized layer blocks the field readers use to power it, so there is nothing to skim. Slide it out and it taps like always. Fits standard credit cards, debit cards, ID badges, and hotel keys.

- Blocks contactless RFID skimming

- Shields 13.56 MHz NFC and payment frequencies

- Standard card size, single card per sleeve

65 dB of attenuation, tested across a broad frequency range up to 40 GHz. That covers cell bands, Wi-Fi, Bluetooth, and the millimeter wave frequencies rolling out with 5G. One cap, the whole spectrum you actually encounter.

Built from: a cotton and polyester outer shell over a silver fiber shielding mesh lining. Breathable, comfortable, and effective.

Fits everyone: adjustable strap, 54 to 62 cm (21.25 to 24.4 in).

Available in Red, Black, Blue, or Tan

It looks like a regular baseball cap. Plain cotton and poly outer, ordinary brim, ordinary strap. Nobody will give it a second glance on the street, at work, or anywhere else.

Under that is near 65 dB of shielding, tested out to 40 GHz. That is enclosure-grade attenuation from a silver fiber mesh sitting right against your head.

The cameras belong to them. These three belong to you, and all three are transmitting right now:

📱 Your phone logs everywhere you go. Data brokers buy that trail.
🔑 Your key fob broadcasts a signal thieves can relay from your driveway.
💳 Your contactless cards answer any reader that gets close.

None of it asks your permission. That's just how they work, until you shield them.

Our new guide covers what surveillance collects, what you can't control, and the six steps for the part you can. Including the ones that are completely free.

At the stove, at the computer, in the lab, on the road: one apron for anywhere RF is in the picture. Soft, generously cut, and comfortable enough to forget you're wearing it.

26 million adults. That's how many people across the US, Australia, and Canada report adverse health effects they associate with wireless radiation, according to a study published this year.

The researchers (McCredden, McLean & Steinemann) surveyed nationally representative samples in all three countries. Across the general population, 12.6% reported wireless sensitivity and 10% reported a medical diagnosis of electromagnetic hypersensitivity. In Australia, nearly 1 in 5 adults reported one or both.

The symptoms people describe range from headaches and difficulty concentrating to sleep disruption and fatigue. The study also found a notable overlap with other sensitivities, like chemical and fragrance sensitivity, which the authors suggest might point to shared mechanisms such as inflammation and oxidative stress.

There’s something deeply calming about staying connected to the earth beneath your feet. This Grounding Mat makes that connection simple.

Built from durable anti static rubber, it does two things beautifully:

Earthing for everyday balance: Rest your hands or feet on the mat to reconnect with the Earth's natural electric potential. It also gives built-up body voltage a path to ground, draining the charge your body picks up from everyday surroundings. Many people keep it near a desk, chair, or bed as part of their daily routine.

Static dissipation that protects your devices: Place it beneath laptops, keyboards, or other static-sensitive electronics to reduce electrostatic discharge.

Every mat ships with a 12-foot grounding cord and a clean two-tone finish, blue on top, black underneath.

Bats navigate hundreds of miles in total darkness. Yet a newly published study found that just thirty minutes of weak radiofrequency exposure left them flying in circles for hours afterward. This is a clear example of how RF at everyday environmental levels can measurably disrupt how a living thing senses its world.

How anthropogenic electromagnetic noise can affect living systems is a poorly understood impact of an increasingly urbanized natural environment, especially when occurring in a sublethal manner. In this study, we investigated impacts of weak-broadband ...
