Amazon is understood to be working on biometric touchless scanning technology which would allow Amazon Go customers to pay with their hand.
The online retail giant has filed a patent at the US Patent and Trademark Office for a touchless scanning system, according to Recode.
Amazon’s application details a scanner device which is “used to obtain raw images of a user’s palm” identifying external characteristics “such as lines and creases” as well as anatomical structures like veins, bones and soft tissue”.
It also proposed placing these scanners at the entrances or exits of locations and being able to associate them with users’ accounts so that “if the user picks an item from an inventory location and leaves the facility, their account may be billed for that item.”
Though this does not necessarily mean Amazon are developing the technology, it supports reports earlier last year that Amazon-owned Whole Foods was testing similar technology.
Many of the investors listed on the application are Amazon Go employees, suggesting that if developed this technology could be installed in its cashierless stores which now trade from 24 locations across the US.
