Amazon will sell cashier-less technology to stores. It is called "Just Walk Out". It means stores do not need cashiers. Shoppers put shopping in their bag and then... just walk out. The software knows how much shopping a customer has and charges the customer's payment card. Amazon has used the software for two years.
The software will cut the number of cashiers in stores. There will be fewer jobs. Cameras will check what customers have in their bag. The customer then gets a bill and receipt. Amazon will make big money from this. Stores want to end complaints about slow checkouts. Amazon said staff can focus on more valuable activities.
