Embodiments describe how this invention addresses different types of payments including contactless physical payments, online payments and vending machine and kiosk payments, with scenarios illustrating voluntary donations, paying a restaurant check with tips from a mobile device, automated actions at the completion of a payment (e.g., issuing a ticket by a ticketing kiosk) etc.
