Google today released an experimental payments app called Hands Free, a service that lets you pay for items in stores without taking your phone out.
The iOS and Android app relies on Wi-Fi, Bluetooth and location services to determine when you’re nearby a participating retailer or restaurant. When you get to the cashier, all you have to say is, “I’ll pay with Google,” and the clerk can confirm your identity with a photo on their end to complete the transaction. The service is only available in the southern end of the San Francisco Bay Area right now, and participating stores include McDonald’s, Papa John’s and a handful of local retailers Google doesn’t list by name.
