RFID mapping: invisible transport flow

While doing some research on the  pervasiveness of technology and ways of mapping this interception of data as a means of invading our privacy, I came across this map of london which animates the flow of Oyster card transactions created for a ‘Sense and the City’ exhibition. The video moves forward at 10 minute intervals over a typical weekday in London counting the touch ins and outs of London commuters and tourists using the RFID chip in their oyster cards. This is a great way to document the scale and flow of people through London and a troubling realisation that every one of these check ins is a piece of data that can be used to track and locate an individuals movements in the city.
