This is a proposal for integration of native Android payment apps into Chrome. The goal of this design is to let any native Android payment app work with any Android web browser without the need for Chrome to link against every payment app SDK in the world.
Motivation
Web payments is a W3C standard API for e-commerce websites to collect payment information from users with user consent. Native Android payment app support should be added to Chrome to let users pay in their preferred way. Web browsers cannot link in every payment app SDK in the world. This is a generic method for any payment app to work with Chrome through Android intents.
