Ultra-thin EMF sticker
A 1.1-inch square that sticks to the back of your phone. It's designed to cut down the wave energy that reaches your body while leaving your signal, Wi-Fi and battery alone.

HaloShield is a passive sticker, barely thicker than a shipping label, made for the back of any wireless gadget. Its job is straightforward: put a barrier between whatever is emitting (your phone, tablet, laptop or router) and the person holding it.
The brand starts from one observation: electromagnetic fields (EMF) surround us all day, coming off phones, computers and Wi-Fi routers, and nobody can see or feel them. The manufacturer cites research suggesting that long-term exposure could affect the brain and blood flow, disrupt certain chemical signals and eventually reach brain cells. That's why it pitches the sticker as an easy, set-it-and-forget-it precaution.
Beneath the black and gold top, several materials are layered to absorb, bounce back or scatter part of the RF energy heading out the back of the device, according to the manufacturer. There's no circuit, no battery and no app. Once it's on, it simply keeps working in the background.
Since most homes run more than one connected device, it's sold in multi-packs. You only need one sticker per device.
It all comes down to a stack the manufacturer calls ShieldCore: three layers, each handling waves in its own way, sealed under a silicone skin.
The base is a weave of conductive fibers, similar to what goes into EMF-shielding textiles. This is the layer meant to catch and soften part of the RF energy traveling from the back of the device toward your hand, thigh or chest.
Right above it, a very thin sheet of aluminum works like a tiny mirror. It reflects and scatters the waves that hit it instead of letting them travel straight into your body. Because it's so small, the rest of the device still sends and receives normally.
A third layer contains a material that gives off negative ions. Everything is sealed under a printed silicone finish that stands up to rubbing, the heat of a charging phone and moisture, so the sticker holds up over time.
Expert opinion shared by the brand
“A well-thought-out take on everyday radiofrequency exposure. The layered physical build makes sense: pairing shielding fabric with aluminum follows basic engineering logic, and the ultra-thin format blends into just about any device.”
No tools, no settings. Plan on about ten seconds per device.
Pop the case off if it's going underneath, then give the surface a quick wipe with a clean, dry cloth. Dust and fingerprints are the enemy here: a clean surface means a much stronger grip.
Lift the liner from one corner without touching the sticky side. Find the center of the device before you bring the sticker in, because placement matters.
Lay it down flat and press firmly for a few seconds. Snap the case back on, then move on to the tablet, laptop or router with the next stickers in the pack.
Good to know: the adhesive is one and done. Take a second to line up the center before it touches down, since peeling it back off ruins the glue.
Straight from the manufacturer's listing. Nothing added, nothing left out.
Start with whatever spends the most time against your body, then cover the gear that broadcasts around the clock at home.
Back pocket, palm, ear, nightstand: no device spends more time near you. Sticker number one goes here.
Pocket-facing sideWorking from the couch, streaming in bed: a laptop can sit on your thighs for hours. Put the sticker on the underside, right where it rests on your legs.
Underside, centered
Cartoons, games, homework: kids tend to hug the tablet close to their stomach. It's an easy step that gives parents peace of mind, and kids stop noticing it almost immediately.
Back of the tabletIt broadcasts day and night, often right in the living room. A sticker on the side facing the room rounds out the setup for the whole house.

| Feature | HaloShield | Basic sticker | Shielded case |
|---|---|---|---|
| Build | 3 layers + silicone | Usually just one | Metal-lined flap |
| Bulk | 28 mm, paper-thin | Thin | Thick and heavy |
| Keeps signal and Wi-Fi | Yes | Hit or miss | Only with the flap open |
| Wireless charging | Works | Hit or miss | Seldom |
| Tablet, laptop, router | Yes | Sometimes | Phone only |
| Keep your current case | Yes | Yes | No |
| Disclosed materials | ShieldCore, layer by layer | Vague “quantum energy” | Depends on brand |
| No battery or app | Yes | Hit or miss | Yes |
| Kids' devices | Ideal, says the brand | Hit or miss | Phone only |
| 30-day guarantee | Yes | Seldom | Depends on brand |
A shielded case still makes sense if your phone is the only thing you care about and the extra bulk doesn't bother you. Where HaloShield stands out is how discreet it is, and how a single pack covers every device in the house. The HaloShield column mirrors the comparison chart the manufacturer publishes: a ShieldCore stack with disclosed materials, no battery, no claimed interference and a format billed as ideal for kids' devices. By contrast, the brand says, plenty of generic stickers talk up “quantum energy” without ever saying what's inside.
Below are the benefits the manufacturer claims for its sticker, passed along as stated, followed by what customers surveyed by the brand reported.
The manufacturer ran its own survey, asking 1,000 customers to use the stickers for 30 days without changing anything else about their routine. Here's the feedback the brand chose to highlight.

Plays nice with my MagSafe wallet
My card wallet snaps onto the back of my iPhone and I figured a sticker would weaken the magnets. I put it under the case, just above the ring, and both the wallet and my charging pad still lock right on. You can't tell it's there.
Still have bars on back-country roads
I'm a crop insurance adjuster, so I spend whole days driving farm country where coverage is spotty to begin with. I was worried about losing what little signal I get. Two months in, no difference at all. Put one on my work laptop too.
Did both kids' iPads before our road trip
We drove to the beach in June and the boys were glued to their iPads for eight hours each way. I wanted to do something small about that. The stickers are still on, nobody has tried to pick at them, and I feel a bit better about it.
Nice product, but measure first
Well made and low-profile. My first one went on a little crooked, and since you can't lift it without wrecking the adhesive, it stayed that way. For the rest I made a tiny pencil mark at the center first and they came out perfect.
Ten-pack covered the whole house
Five of us, so four phones, a Chromebook, my wife's laptop, two tablets and the router in the den. That left exactly one spare for when our youngest gets her first phone. Took ten minutes total and nobody has noticed any change.
Even I could handle it
At 74 I don't want anything that needs pairing or charging. My granddaughter stuck it on during a visit and I haven't given it a thought since. The phone works the same as always, which is all I asked for.
Shows through a clear case
Through my clear case you can see the black and gold square. I actually kind of like it, but if you want it totally hidden, use an opaque case. Signal and battery are exactly the same as before.

The manufacturer says no: it reports zero interference with LTE, 5G, Wi-Fi, Bluetooth or battery life. The sticker only covers a small patch on the back, so the antennas keep doing their job.
Yes. It is slim enough to slip under a soft or magnetic case. If you would rather see it, you can put it on the outside of the case instead.
Just one. Each sticker covers a single device, which is why most households grab a 5, 7 or 10-pack to handle every phone, tablet, laptop and router in the house.
With no battery or electronics inside, there is nothing to wear out, and it stays put for months. The adhesive is single-use, though, so peeling it off to reposition it is not a good idea.
Center it on the side that faces your body: the back of a phone (the side against your pocket), the underside of a laptop, the back of a tablet.
Yes, it works on the back of kids' tablets and phones. Once it is flat and pressed down, they tend to forget about it. Apply it yourself and keep spare stickers away from small children.
The manufacturer says it does not block wireless charging. With a magnetic charger, keep the sticker centered and clear of the magnet ring on your case.
