The tracker, likely called the Galaxy smarttag, has been leaking out over the past month. There’s speculation it could be announced alongside the Galaxy S21 later in January.

The Galaxy smarttag would use Bluetooth to connect with nearby devices and broadcast its location. It’ll be powered by a replaceable button cell battery, according to a regulatory filing.

The smarttag is a small square with rounded corners and a hole at one edge for slipping a keychain or lanyard through. Photos of the device filed with Taiwan’s telecom regulator were publicized by 91mobiles.

Samsung released a tracker back in 2018 that connected to cell phone networks for continual tracking. In October, Samsung launched an app that helps owners of its gadgets locate their existing devices using Bluetooth.
