TfL to track Tube users in stations by their MAC addresses

Yes, by design Apple IOS 8 devices randomise the MAC under some conditions to defeat this kind of identifaction. Note: by default it's fairly poor protection: it only works if you aren't using the device.

Also, this is the second time I've seen claims that London is using WiFi tracking. Most of the traffic tracking in the world is done using Bluetooth, so I'm wondering what the attraction is for WiFi here.
