Bluetooth trackers appeared a few years ago, after Bluetooth technology incorporated low energy mode, allowing a simple Bluetooth-enabled device to work for a long time while being equipped with a small battery.

This means that you can pick up a cheap Bluetooth tracker and use it for more than a year before needing a replacement.
