Android Pay appears to be testing the ability to see all card purchases, even those not done on your phone — 9to5Google — “The Android Pay app appears to be testing out a new feature for ‘full purchase history’. In short, this new feature pulls your entire transaction history from your card and displays it right alongside Android Pay purchases. This new setting on Android Pay appears to only work for specific cards, though. In this first case, it works with an American Express Cash card.”
