Transaction flows

A Google Pay user can purchase and use tickets at any point of sale within the transit system. This includes purchases made at vending machines, when users tap their mobile device at a turnstile, or when they tap their mobile device at the platform. For distance- or zone-based fares, Google Pay allows users to tap out at their destination.

Figure 1 illustrates the possible user flows:

Transit operators can also support daily, weekly, or monthly passes for open loop payments on their systems. This requires operators to link the pre-purchased pass to the user's payment credentials. When the payment credentials are used, the transit operator recognizes it as a pass. Alternatively, at settlement time, transit operators can charge the payment credentials for the price of a daily pass instead of each individual trip taken throughout the day.
