Just over half of Amazon Fresh stores are equipped with Just Walk Out. The technology allows customers to skip checkout altogether by scanning a QR code when they enter the store. Though it seemed completely automated, Just Walk Out relied on more than 1,000 people in India watching and labeling videos to ensure accurate checkouts. The cashiers were simply moved off-site, and they watched you as you shopped.
Nah, Amazon Fresh is just a regular grocery store. They still have a bunch of other stores with this technology, especially third party vendors i.e. other companies in stadiums and airports mainly who have a contract with Amazon.
