Google recently announced its new experimental mobile payments service that allows a person to make purchases without having to touch their phones. 

Hands Free is an app that will allow users to buy items using only voice commands. Google is now testing the app in a few stores in the San Francisco Bay area, according to Mashable. 

Instead of using the Near Field Communication (NFC) chip that powers many touch-to-pay platforms like Android and Apple Pay, the iOS and Android app uses a combination of Bluetooth, Wi-Fi and location services to detect when you're at a store that is set up for Hands Free. This also means you can use Hands Free even if your smartphone doesn't support NFC payments.

The payments, which Google first introduced last year at its I/O Developers Conference, is still very much an experiment but one that could represent "what the future of mobile payments could look like," according to Google.

While Hands Free is only available at a few McDonald's and Papa John's locations in the Bay Area to start, Google notes it's already seen widespread adoption of Android Pay, its NFC-based payments system it debuted last year. The company says it's been averaging about 1.5 million registrations a month and that the payments are already supported at more than 2 million locations.
