JeroenE nice! very excited to test the future way of paying for public transport next week, got everything set up as well through the 'Oyster and Contactless'-app from TfL so I can keep a travel log. (which is not strictly needed, required or necessary for tourists, but I like it anyway)
Tuesday 26 nov, 08:04 GMT.: Special Update from, Victoria Station, London, UK: Yes I can confirm, Maestro Cards from bunq work with Oyster and Contactless including in combination with Apple Pay, just tapped in with my iPhone for an overgrond train to another part in London without any problems.
