Oyster card backlash begins in Hackney

Hackney, and East London in general, seems to be the source of a
decent amount of subversive activity.

This picture is of a small flyposter I spotted near London Fields this
afternoon on my way back from a lovely day wandering around the
Columbia Road, Brick Lane and Spitalfields area, my favourite bit of
London.

It would appear the information Transport for London's Oyster card is
capable of storing about the user has some people on the defensive.
Are TfL responsible for introducing ID cards on the sly? If the recent
breakdowns in the system are any clue, the Government could well be
involved!
