About WorldTag: Use Apple device IPHONE,IPAD's own Find My APP to bind the anti-lost device. The anti-lost device can be installed on key chains, wallets, bags, electric cars and even pets. If there is Apple device around the anti-lost device, the location information of the anti-lost device can be reported to the Apple server network, and then we can Find our lost key chains, bags, wallets, pets, etc.

Working principle: When the WorldTag is separated from the bound Apple device, it will automatically search for the surrounding Apple devices through Bluetooth and send signals to it. The Apple device will record the information of the WorldTag and upload the current location to the Apple Find My network. At this time, you can query the current location of the worldTag through the bound Apple device. In theory, the more Apple devices around, the more accurate the positioning, the more timely the location update! And achieve the function of preventing loss.
