Ever since it became available in the US in September, you've been able to use Android Pay at supported merchants across the country to buy goods. But starting today Google's new payments service is expanding to cover things you buy from within Android apps too.
The search giant says there are now over a million physical retail locations in the US where you can use Android Pay, so this seems like the logical next step.
A bunch of apps are already supported, and the whole buying process is as simple as it can be. You tap the Android Pay button in your favorite app, confirm your information, and that's it. You've made a purchase through Android Pay inside an Android app on your phone. So you won't ever need to pull out your credit card to enter its details into a form again. And just as is the case for things bought from brick and mortar stores, Google doesn't share your card's details with the merchants.
A few apps are offering limited time discounts if you buy stuff in them and checkout using Android Pay. You can save $20 on OpenTable dining, or get $10 off a Lyft ride, $10 off DoorDash, or 30% off Vinted. To view all the offers, go to this link (which will hopefully be up in a bit, as it doesn't seem to be live yet).
Google has also announced that it's taking Android Pay to Australia in the first half of 2016, with more countries to follow.
