Android users have been able to complete purchases in two clicks for a while after the Instant Buy API launched about a year ago. Google has now announced that the same 2-click purchase function is now available for iOS users.
With the instant buy API, iOS devs can now integrate Google Wallet checkout into their apps. The feature will allow users to access shipping and credit card info that is stored on the cloud. The user's payment and shipping details will only be shared with the merchant after they decide to purchase.
The shared payment details are then run through the retailer's normal card processor. Google charges no fees for the service. Google is hoping that its checkout service will help keep mobile shoppers from abandoning their carts due to a complex shipping and payment process.
