Waffle-homestyleGoogle really wants to revolutionize mobile payments. It was a pioneer in this area with Google Wallet, which will be rebranded as Android Pay at some point in the not-too-distant future. It is also working on a completely hands-free payment feature, which will be available soon as a trial in some San Francisco McDonald’s and Papa John’s locations.

But what about paying with a photo? Yes, a photo.

According to this tweet from Google Photos, that’s exactly what Google has in mind.

I’m not quite sure what to make of this, but it seems like an interesting concept. Would you designate one of your Google photos as a security photo to authenticate yourself? Would your phone generate a QR code that a cashier could scan and add it to your photos?

I guess we’ll find out on July 29. In the meantime, I really want a waffle now. Or a wafel.
