Global Intelligence claims its Cybercheck technology can help cops find key evidence to nail a case. But a WIRED investigation reveals the smoking gun often appears far less solid.

Well, crap. I just looked it up. Looks like phones will send out your MAC address when looking for WiFi networks to connect to, and they more or less always search for WiFi, unless currently connected to WiFi.
So - yeah. Same issues with Bluetooth.
And some newer consumer routers do all sorts of funky things under the hood in the name of security, which includes sending information about traffic back to their corporate home base. That could easily also include MAC addresses of passing devices. (Or telling the manufacturer every site you visit. Very fun now that the latest trend in routers is to require cloud connections and accounts, so your identity with them is ‘known’.)
