You May Have To Face Up To A New Way Of Paying For Goods And Services
Sara Stewart strolls into a small Mexican restaurant in Los Angeles and orders a torta, a type of sandwich.
To pay she simply looks at her reflection in a small LCD screen attached to the cashier's counter. Then to add her preferred amount of tip she flashes a quick peace sign at the monitor.
The entire process takes less than five seconds, and is entirely contactless. Moreover, Ms Stewart doesn't need to carry her mobile phone or bank card with her, or show any form of identification, or even enter a pin number.
Welcome to the futuristic world of facial recognition payment. It might sound like something from a science fiction movie, but this kind of transaction is already happening millions of times a day across China's major cities.
With the technology now being introduced in the US, and other countries such as Denmark and Nigeria, are we all going to be using it within a few years' time? And, are there data security and privacy issues that we should worry about?
Ms Stewart, an 18-year-old university student, says she has no such concerns. "I feel like technology is moving so fast that people don't even think twice about using something like this.”
Sara Stewart holds up a peace sign, which, as the system recognises, means that she wants to pay a 15% tip
"Our phones already read our faces, and our faces are already all over the internet, so I don't think it really makes much of a difference [to someone's security]. It's faster, more convenient, and safer... and you don't have to worry about leaving your phone or cards at home."
She uses facial recognition payment, via a US tech start-up called PopID. You sign up via its website, by uploading a photograph of your face, which is stored on the firm's cloud-based system. You then link your account to your bank card.
In addition, you can choose to use PopID's hand gesture tipping tool. Ms Stewart has set this at thumbs up for 10%, the peace sign for 15%, and the shaka or "hang loose" sign for 20%.
PopID is based in Los Angeles, and is now used by about 70 independent restaurants and cafes across a handful of US cities, mainly on the West Coast.

The firm's chief executive John Miller says: "Our view is that using your face to pay is no different [than using your phone]."It's just another way to identify yourself. The [digital] picture [taken at point of sale] is destroyed immediately, and the data isn't shared with anyone."In fact, he argues that it's less intrusive than paying by your mobile phone, because a phone can track your location at all times via GPS. He adds that the photos stored by PopID are mathematical maps of unique facial vectors, not actual photographs.
Currently PopID requires the user to temporarily lower his or her facemask, but the firm says it is updating its systems so that this will not have to be done in the future.
