Humans regularly pay for having their photo taken (when it’s horrible and it gets posted on social media, or when looking back and wondering why you ever thought that hairstyle was a good choice). But, following on from a tease at its I/0 event, Google decided to let people pay with a photo to promote the enhanced search functionality of its upgraded Photos app.
Unsurprisingly, money is still the favoured form of payment in most locations, but there are now a few other ways to pay and many brands and businesses seem to see social media as a new currency and ask users to tweet, like, post a selfie or share something for untold rewards.
Mastercard is even trialling technology that lets people pay with your face.
