Despite Android Pay's promise of simplicity, getting loyalty points is still a small hassle -- you either have to carry the store's card or have the cashier scan it from your phone. Walgreens has revealed that it's the first retailer to integrate rewards points directly with Google's payment system. All you need to do is place your phone near the payment terminal to scan in your card, then tap it again to actually pay. "Walgreens customers can speed through the entire checkout process in as few as two taps with their Android phones," says Google Senior Director Pali Bhat.
