I don't actually know what "we cap £" means. I do know that it always seemed irritating that the Metrobus worked by having to buy a ticket in advance at fiddly little machines next to the stops, and that being able to just buy a ticket by tapping a card once you were on the bus would seem wildly futuristic if I hadn't had a Oyster card decades ago in London...
Having just tried to read the 2,500-ish word explanation of Tap & Cap, I'm still not sure exactly how to use it, but hopefully it at least means that Bristol bus drivers will no longer swear at you if you don't happen to have exactly the right change sorted out in advance...
