Seattle-based Amazon has announced it is expanding its palm-scanning payment technology to its grocery in Redmond, its bookstore in University Village and its 4-Star store in Southcenter.
Customers link their handprint to a credit card and wave their hand over a scanner to pay for merchandise. Amazon Go convenience stores have replaced cash registers with cameras that track which items customers remove from shelves for billing to their Amazon accounts.
While convenient and fast, the technology has raised privacy concerns among critics. Regardless, the technology could foretell another way that retail is likely to evolve on a broader scale.
