Amazon said yesterday that its Amazon One technology - which allows people to enter Amazon Go stores and pay for their purchases with just a handprint, not the app - is being expanded to additional stores in Seattle.
According to the story, "Amazon One will be added as an entry option at the Amazon Go location at Madison & Minor beginning today, February 1. In the coming weeks, we will also add Amazon One as an entry option to two more Amazon Go stores in Seattle at 5th & Marion and Terry & Stewart. With this expansion, a total of 8 Amazon physical retail stores in the Seattle area will offer Amazon One as an option - including select Amazon Go, Amazon Go Grocery, Amazon Books, and Amazon 4-star stores."
In the past, entry to an Amazon Go store depended on having the Amazon Go app installed on your smart phone. But by linking the account to an individual's handprint, Amazon is making the process that much simpler.
