TfL to track Tube users in stations by their MAC addresses

Have WiFi turned on as you enter the Tube station, and then turn it off in the middle of your journey - enough people do this and it'll look like commuters have simply disappeared into the rail network somewhere.....

Until the Oyster ID or Underground ticket ID that was logged at the same time as the WiFi MAC address shows up at another exit, of course, at which point they'll have a nice video of the individual who has by then been marked as suspicious.

That's the second problem: you don't really know what ELSE they will use this data for because the last time a government department decided to break the law regarding data collection they simply retrospectively changed the law. Now they've gotten away with it once there's every reason to suspect they will do that again..
