A Tracker That Talks

Imagine this scene: Your furry friend accidentally runs out of the yard and is found by a kind stranger. As they kneel down to check the collar, they don't see an ordinary ID tag. Instead, they see a clearly displayed E-Ink screen that reads: "My name is Buddy. If I'm lost, please call 138****1234 to contact my owner." Next to it, a QR code that scans directly to a contact page.

This isn't science fiction. This is the reality brought to you by the Union Smart Find My + E-Ink 2-in-1 Tracker Card.

We understand that traditional Bluetooth trackers help you locate lost items, but they share one common pain point: they only help you search; they don't help the finder contact you. Union Smart Tracker Card was created precisely to solve this problem.

E-Ink Display: More Than a Screen, It's a "Never-Disappearing" Contact Method

Bistable Display Technology: Information Visible Even Without Power

The most unique technical feature of E-Ink screens is bistable display. This means power is consumed only when the screen content refreshes. Once the display is fixed, the image remains permanently even if power is completely disconnected.

What does this mean? Even if the tracker's battery dies, the emergency contact information on the screen remains clearly visible. For lost-and-found scenarios, this is a critical safety net.

NFC Refresh: Update Content Without Draining Battery

Want to change the contact information or photo on the screen? Simply edit the content in the mobile app, then tap your phone to the card. Using NFC technology, your phone provides a tiny amount of power to refresh the screen—instant update, with zero drain on the tracker's own battery.

This means you can:

Display "If lost, call Mom" when going out with children

Show hotel information and temporary contacts during travel

Display emergency medical alerts and family contacts for elderly wearers

Sunlight Readable, Blue-Light Free

E-Ink screens reflect ambient light rather than emitting their own like phone screens, making them more readable in direct sunlight. Additionally, they produce no harmful blue light, making them safe for children's use without worrying about eye strain.

Ultra-Low Power, Ultra-Long Battery Life

Since E-Ink screens only consume power during refreshes, the Union Smart Tracker Card can achieve months or even longer battery life. A small rechargeable battery provides extended periods of worry-free protection.

Beyond Kids: Full-Scene Smart Protection

The beauty of the Union Smart Find My + E-Ink Tracker Card is that it can accompany almost every important item in your life:

Child Protection

Attach to a backpack or slip into a pocket. The screen displays your phone number—if a child wanders off, anyone who finds them can call you immediately without needing any app. Real-time positioning lets you know your child's location at all times, and left-behind alerts prevent them from straying too far.

Pet Tracking

Attach to a collar. If your dog gets spooked and runs off during a walk, a kind stranger seeing the contact number on the screen can notify you immediately. With the Apple Find My network, even if your pet runs far away, hundreds of millions of Apple devices worldwide can assist in location tracking.

Luggage Protection

Attach to your suitcase. While traveling, the screen displays your name and contact information. Wrong luggage at the airport? The finder can contact you after seeing the screen. If luggage is delayed or lost, the global positioning network helps track it down.

Backpacks/School Bags

Kids leave backpacks on the playground; you leave yours at a café. The left-behind alert notifies you when you've moved beyond a certain distance. Contact information on the screen also makes it easy for finders to return your bag.

Wallets/Card Holders

Ultra-slim design fits easily into card slots. Never worry about leaving your wallet at a restaurant again. If someone finds it, the phone number on the screen makes return incredibly simple.

Keychains

Attach to your keys. Can't find them? Trigger an audible alert from your phone. Keys lost outside? The Find My network helps you recover them.

Senior Companion

For elderly family members with memory issues, the screen can display not only contact information but also medical alerts like "I have high blood pressure—please contact my children if needed."

Important Documents

Attach to passport holders or important document folders for an extra layer of protection when traveling abroad.

The Warmth of Technology: Making Kind Returns Simpler

We developed the Union Smart Find My + E-Ink Tracker Card based on a simple belief: technology should make the world a warmer place.

Traditional trackers assume the scenario is "you lost it, you find it." But we know that often, lost items are found by others. Instead of leaving a kind person holding your wallet with no way to contact you, why not let the item tell them: "Please call this number—someone is anxiously looking for me"?

This is what E-Ink technology brings—giving lost items a voice, giving every loss one more chance of being returned.

Whether it's children, pets, wallets, or luggage, the Union Smart Tracker Card quietly guards them all, using that line of text on the screen to build a bridge home for you and your cherished belongings.
