Photo of a mobile boarding pass (a 2D Aztec code bar code on an Orange San Francisco smart phone) on top of a paper boarding pass, printed after online check-in, for a KLM flight. UK passport in the background.
I blurred some details on both boarding passes (name, date, ticket number) and I altered the mobile boarding pass by making some rows and columns of the 2D bar code black, trying to ensure that my details cannot be read.
