Some implementations provide a method that includes: generating an association, at a mobile device, between a government-issued identification document of a user and a mode of payment; receiving, at the mobile device, a presentation of the government-issued identification document of the user to support a request for payment; validating whether the presented government-issued identification document is a valid identification of the user; and in response to validating the presented government-issued identification document, proceeding with payment by using the mode of payment.
