Can I do anything useful with these tracking bracelets?

So far in the game, I've found four tracking bracelets, belonging to:

• Alex Yu
• Sylvain Bellamy
• Danielle Sho
• Kirk Remmer

They don't get automatically tossed in the recycler like other junk items, but they also aren't orange like quest items. I haven't found any use for them. Can anything be done with them?

So far the only known use for them is to drop them in a location so you can easily backtrack to that location later.

You can use the bracelet to mark some box or location, so later you can find this location again. Couldn't find any other use for it.

I have read rumors saying it might be sidequest bound, but they got instantly debunked by others. In this reddit thread someone mentions to keep them as he says the following:

Collect them and something cool will happen

Finally, an article on Kotaku quoted the 1.04 patch notes, confirming what most people already suspected:

“Tracking bracelets are now sent to Recycler with ‘Transfer all Junk.’” In other words, you never needed to carry a discarded tracking bracelet around in the first place. This changes everything.

Once you find the bracelet, its owner is marked as "found" on security terminals, which counts towards your statistics and related achievement. That's all I've found during two playthroughts, and I doubt there are any other uses.

Interesting thing is that those persons bracelet belongs to are usually not found in game by normal means, e.g. you encounter Danielle only indirectly, seeing her through window of station.
