From Wired to Wireless Labeling

The Problem: Battery Fatigue

Every smart label eventually dies. Changing hundreds of coin cells across a warehouse isn’t just tedious — it’s costly and unsustainable. And updating them via Bluetooth or power-hungry screens only makes it worse.

The Breakthrough: Harvesting NFC

This e-paper panel draws its power directly from the NFC field of your smartphone. A simple tap transfers both energy and image data — no battery, no pairing, no separate power source. Just instant, vibrant updates in red, black, and white.

The Outcome: Endless Possibility

With no battery to replace and updates happening over thin air, these displays can live anywhere — from smart shelf labels that never need maintenance to inventory tags that always show the latest info. Your IoT just got a lot quieter.

Questions and answers

Does it really never need a battery?
w
Wanelo · seller

Yes — it has no battery slot. All power comes from the NFC field of your smartphone during the update. The e-paper display uses zero power to retain an image.

Which phones can update it?
w
Wanelo · seller

Any smartphone with NFC and the companion app. iPhone 7 and later (with iOS 13+) can read NFC tags, but earlier iPhones may be limited. Most Android phones with NFC work out of the box.

Can I show photos or just text?
w
Wanelo · seller

You can send any image — but it will be dithered into red, black, and white. Photos work surprisingly well, and logos, QR codes, and text look sharp. Full-color photos aren’t possible.

How long does an update take?
w
Wanelo · seller

Typically less than one second. Place your phone within 4 cm, tap the update button, and the image transfers instantly.

Is this cheaper than battery-powered smart labels?
w
Wanelo · seller

Over time, yes. There are no battery replacement costs, and zero electricity consumption. For large deployments, the savings add up quickly. The hardware pays for itself in its first year.

Can I mount it outside?
w
Wanelo · seller

The display is not weatherproof, but works well under a covered awning or inside a protective enclosure. Avoid direct rain.
