KITKAT, we got you. (No, we didn’t eat them.)

So… we heard some KITKATs went on a little adventure. 🏃‍♂️💨
Inventory doing a magic trick? Not on our watch.

We make two things that every chocolate lover (and supply chain manager) needs:

🔹 Custom-shaped trackers
Want it to look like a KITKAT wafer? Done.
Stick it on, and your phone becomes a chocolate-finding radar.
“You are 3 feet away from your snack… I mean, inventory.”

🔹 Temp & humidity sensors
Because nobody likes a sweaty chocolate bar. 💦
If the warehouse gets too hot or humid, these tags scream before your KITKAT does.

We’re a factory. We don’t make the chocolate.
We just make sure it doesn’t ghost you. 👻🍫

Drop a 🍫 if you’d trust your snacks with us!

The E-Ink Difference: Information That Stays, Even When Power Fades
Most trackers only work one way: they help you find your stuff. But what if someone else finds it first? That's where the Union Smart Tracker changes the game.

Bistable Display Technology
E-Ink screens are bistable, meaning they consume zero power to maintain an image. Once information is displayed, it stays there—even if the battery dies. In a lost-and-found moment, that's a lifeline.

NFC-Powered Updates
Need to change the contact info? Update it in the app, tap your phone to the card, and the screen refreshes instantly—powered by your phone, not the tracker's battery. Zero drain. Infinite flexibility.

Sunlight-Readable & Eye-Safe
Unlike glowing phone screens, E-Ink reflects ambient light, making it crisp and clear even under direct sun. No blue light. No eye strain. Just pure readability.

Ultra-Low Power, Ultra-Long Life
Because the screen only uses power during updates, the Union Smart Tracker runs for months on a single charge. Set it and forget it—until you need it.
