🔍 Lost your keys again? Can't remember where you left your bag? Don't worry—this "card" knows better than you do!

✨ Seen a tracker this thin?
At just 1.5mm thick, it's the size of a bank card! Just slide it into your cardholder, passport case, or laptop sleeve. Say goodbye to bulky trackers!

📱 Apple users, rejoice!
It works natively with the Apple Find My network. Open the "Find My" app and see exactly where it is. Android users aren't left out—it also works with Find Hub!

🌊 Tough as nails.
With IP68 waterproofing and resistance to extreme conditions, even a sudden rainstorm won't ruin your day (or your tracker).

🔊 Can't find it? Let it "scream"!
It packs a 100dB speaker. If it's hiding in the couch, it will definitely let you know.

🔋 One charge lasts 3~5 months.
Tired of constantly charging gadgets? Just align it with the charger when it's time—effortless.

👉 Whether you want one for yourself or need a gift for that friend who always loses things, this little card is a total game-changer.

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.

We have. And it terrified us.
So we created the NFC Pet Smart Tag — a tiny guardian for your furry family member.
✨ If someone finds your pet, they just scan the QR code or tap their phone on the tag — your contact info pops up instantly.
✨ No app download needed (yes, it's that simple).
✨ You can store your pet's name, medical info, allergies, emergency contacts — all in one place.
It's a small tag that could be the difference between lost and found.
