Google unveils 'buy' button, host of new shopping features

Google on Wednesday unveiled a new feature called "Purchases on Google," which allows shopper to buy items directly from mobile search ads.
The eagerly awaited "buy" feature, which Google said it was testing with a few retailers, uses saved payment credentials from the user's Google Account for transactions.
Both Google and Facebook have been stepping up efforts to advance location-based technology as consumers spend more time on smartphones.
The additional information will be available on Google Chrome for Android this month, with iOS support to follow in the coming months, the company said.
Google also said its Google Now service would now offer location-based information, including on discounts on items and the working hours of stores a user is close to.
