Google has developed a method that allows users to pay with the combination of a smartphone app and facial recognition. The method, called Hands Free, makes it possible for users to keep their phone in their pocket.
Hands Free is available for both iOS and Android and uses Bluetooth Low Energy, WiFi and location services to determine whether an user is nearby a participating store. To make a payment the customer needs to tell the cashier to use the Hands Free method. The cashier then asks the for the customer's initials and uses a photo that has been added to the Hands Free app to confirm the customer's identity. When the cashier confirms the transaction the customer immediately receives a message on his phone.
At some stores Google is also experimenting with automated facial recognition. In these stores a camera determines the identify of a customer based on the Hands Free picture. Google stresses that all pictures taken by the camera are immediately deleted. The search giant also argues that this way of paying is safe because credit card/debit card data is not shared with the store and because users are warned when the system detects suspicious transactions.
Hands Free is currently tested in several Mcdonald's, Papa John's and some restaurants in South Bay, Los Angeles. Google offers up to $5 to stimulate users to make their first Hands Free purchase.
