"Last year, TfL collected Wi-Fi connection data (MAC addresses) at 54 tube stations in zones 1-4 over a four-week period"
“The TfL Wi-Fi trial was a really good example of a public body coming forward with a plan, a new initiative, consulting us deeply and doing a proper privacy impact assessment… [It was] a good example of privacy by design and good conversations with the regulator to try to get it right.”
+++ "Following our meeting, it has emerged that TfL will use this data to generate £322 million in advertising revenue over eight years" +++
"However, TfL should have been more up-front about this aspect of the trial and the financial benefits it hopes to achieve using its customers’ data. This information was omitted from the posters at tube stations, for example, which simply said “Transport for London will collect WiFi connection data at this station to better understand journey patterns and improve our services.”
"There are risks that some customers might think that they have been taken advantage of."
