The ultimate public transport payment experience is here As of 2nd Dec, Express Travel with Apple Pay is active in London on all Transport for London’s stations and buses, and usable with Citymapper Pass . We’ve been waiting a long time for this ultimate user experience, where a mobile device and app can support the entire end-to-end journey of planning and payments. Express Travel makes this even more seamless since public transport readers will automagically detect Pass without the need to open one’s phone.
