We are being assimilated.
The technology, which has been available for the last couple of years in some form, is capable of tracking a smartphone using the unique identifier that it broadcasts via Wi-Fi. It is the same as that used by beacons which track smartphones using the unique Bluetooth identifiers every smartphone puts out when the wireless communications service is switched on.
I keep the GPS on my phone turned up when I’m not actively using it. Think I’ll start doing the same with the Wi-Fi.
It may not do much, but at least I don’t have to help our mercantile Big Brothers.
