As the purpose of the scheme is to reduce boarding times and as it

that they're probably not including crew-operated routes in the scheme.

But they're installing ticket machines at stops on Piccadilly that are
only served by crew-operated routes.

You can also purchase one-day bus passes from the machines; these are
not available for purchase on-board the bus.
