Apple has been longtime working on bluetooth tracker/ tile aka by company AIRTAG. 

As per a report by noted tipster Jon Prosser, Apple will launch the AirTags November. The tipster says that the final testing for the device will be completed by November 6 and that the company would start shipping the device within 30 days of that timeline.

It is worth noting that the tipster in a separate tweet had said that the iPhone maker will be hosting a special event in November this year wherein it would be launching a line of Mac computers that are powered by its own ARM processors. The tipster said that Apple is expected to host the Mac Event on November 17.
This is not the first time that we have heard about a launch date for the AirTags. While some reports in the past have hinted towards the company launching the device in 2020. Others have said that the company may launch the Bluetooth tracker in 2021 along with a new MacBook Pro, a new MacBook Air, an entry-level iPad and new Mac computer.
Meanwhile Apple, has remained tight-lipped about the matter. So, for now all we can do is wait for the company to shed some light in this regard.
