First, users must download a corresponding iOS or Android app, enter in their initials, choose a payment method (both debit and credit are supported), and then upload a photo of themselves. The app relies upon Bluetooth LE and WiFi to gauge when a particular customer is near a checkout kiosk. When a customer approaches the checkout counter, the app sends over the individual’s photo and initials to the point of sale system. The user tells the cashier that they will “pay with Google,” and gives their initials to the cashier, who then inputs that and the transaction is closed. This process uses an in-store camera to automatically confirm the identity based on the picture stored in Hands Free profile.
