I've had two occasions now at two separate merchants to use the Level Up app in my Win 10 phone to pay for lunches. I noticed on the white cube scanner a logo that arguably might be MS's four squares and one of the merchants I saw was using MS on the register terminal. But the app is available for Android and IOS as well.
Is Level Up a step up in MS using phone payment system?
