Huawei recently filed a patent called Huawei S-Tag. It is a patent of grade 9/10/14, which means: “Smart watch; smart rings; wearable trackers; data processing apparatus; pedometer, etc. ”

Surprisingly, the description of the patent lacks the category of “electronic tags”. For example, Huawei may be working on a new wearable device equipped with an S-Tag function, such as a smart ring, bracelet, and more.

Smart tags are tracking devices that attach to things. They use Bluetooth for close range, and when you cannot find keys, wallet or anything else attached to the smart tag, a signal will come to the phone telling the location.

If the tag is out of Bluetooth range, companies use clever tricks like connecting branded devices to the network to find the device with the lost tag. The idea is simple and effective.
