Starbucks is a free mobile application that acts as a digital rewards card and payment method for Starbucks coffee shops around the world. It allows you to register your Starbucks cards and collect stars for every purchase you make using the application. Just scan your QR code at the register or even order ahead and skip the line. With a full menu to choose from, you order will be made just the way you like it and waiting for you when you arrive. When you earn enough stars, use your rewards to get free drinks and food on your next visit by scanning your app.
