Smart Wallet & Tags

Overview

Smart Wallet & Tags is a family of slim Bluetooth + Ultra-Wideband trackers — a card-shaped tag that lives in a slim leather wallet, a round fob for keys, a square tag for luggage, and a tiny sticker for laptops or remotes. Lose any of them and your phone walks you straight to it.

Designed for the dozens of small moments — sprinting back to the café for a wallet, hunting for keys before school run, hoping airport luggage actually made the connection. Each tag pings the global crowd-find network (1B+ phones) so it stays findable even when you are not nearby, and on-device UWB gives precision metre-accurate arrows when you are.

BLE 5.3 + UWB for both crowd-find and precision direction-and-distance
Separation alerts — phone buzzes when you leave a tagged item behind
1-year coin-cell battery · replaceable on the larger tags, rechargeable card variant
Privacy-first — rotating IDs, E2E encrypted pings, anti-stalk detection built in

How It Works

The diagram above traces one lost-and-found cycle. Hover any module to see live tracker data.

Wallet & tags are slim Bluetooth + UWB beacons in 4 form factors — embedded in the leather wallet, on the key fob, on luggage straps, or as a peel-and-stick disc. Each beacons every few seconds.
Find precisely — when in BLE range, your phone shows distance; if your phone has UWB too, it draws a live arrow ("2.4 m, northeast") plus haptic warmer / colder feedback.
Find-My network — outside BLE range, any opted-in phone in the global network anonymously pings the tag and uploads an encrypted location only your account can read.
App & family lists every item, supports shared family items, lets you set Notify-When-Found searches, voice-controlled "ring my keys", and Lost Mode with a public contact card.
