Google has finally started rolling out its new payment app as the result of Google Wallet and Android Pay collaboration. The company announced about the Google Pay, back in January this year and started pushing the app to Android devices from Tuesday. Google also shared some details about the Google Play app on the website mentioning its features and how it works. The search giant has also released some YouTube videos to give tutorials on the app like how your info stays safe, how to pay in stores, and, how to add and verify a card.As Google Pay is now available in the Play Store you can see the app&#39;s interface in the shared screenshots. The app is divided into two sections &lsquo;Home&rsquo; and &lsquo;Cards&rsquo;, where &lsquo;Home&rsquo; shows the recent payment activity, nearby offers, and stores with a card style interface. On the other hand, the &lsquo;Cards&rsquo; tab contains all your debit/credit and another card details along with rewards. Although, the functionality of the app remains unchanged, users can make payment or transfer money easily. With the launch of the unified payment app, Google intends to compete with Apple Pay and Samsung Pay.Google made it clear that it will be taking its new payment platform too seriously and holds big plans for the app in future. The tech giant also noted that the Google Play will be soon integrated with other Google products including Assistance and Chrome. In addition, the user will also be able to use save cards from Google Pay across a variety of websites and apps while using Android devices or Chrome. Google launched Android Pay in 2015, for making payments at stores and then later on expanded the app support to banking apps and in-app purchases.For now, only UK and US users will be able to avail the money transfer facility using Google Pay and there is no information available on when a similar functionality will be made available for users residing in other countries. Along with this Google Play can also be used to pay for transit in cities including London, Portland, and Kiev. However, the transit functionality depends on where you live and how your city&#39;s transit works.With the launch of unified payment app, the company has also rebranded Google Wallet app as Google Pay Send. The tech giant has redesigned the app in order to counterpart it with the rest of Google Pay.
