After first teasing the service last May, Google is extending their Hands Free payment to South Bay inhabitants near San Francisco and limited restaurants including McDonalds and Papa John's. The app, which is compatible with both Android and iOS devices, enables people to forego the tap and pay method by letting you pay with your face or by saying your initials out loud.
Biometric payment systems are not new, but Hands Free by Google allows you to securely pay without lifting a finger (or finger print). Technology such as Bluetooth low energy, location services, wifi and other smartphone sensors make it possible to pay in-store without having to dig around for your wallet or cards. You can simply tell the cashier "I'll pay with Google" and they will be able to confirm your identity based on your profile picture and initials.
