Google has begun a limited roll out of their new apps and service, Hands Free. The testing area is limited to a select number of retailers and for those who live or work in the South Bay area, just south of San Francisco, California. Generally it covers Mountain View, Sunnyvale, San Jose and Palo Alto. The idea, as the name suggests, is that you can complete a purchase completely hands free – no phone or smartwatch in your hand or on your wrist required. The app utilizes Bluetooth to communicate between the point-of-sale terminal and your phone in your pocket.
