Google Wallet Instant Buy
Google Wallet Instant Buy API allow merchants to access customer payment data stored in the cloud. It provides great convenience and security to the user. Whenever the user taps on Buy with Google on a merchant site, they will see a dialog where they can log in using Google and pay with a payment method they've stored in Wallet. Instant Buy masks the real payment info and the merchant will only get a one-time payment code.
Instant Buy was built and optimized for the web. Its complicated interaction and drop-down selectors were really clunky to use on mobile. With the increasing trend of mobile shopping, the goal of this project is to re-create Instant Buy's UX for mobile (iOS and mobile web).
