In US supermarkets: Amazon wants to monitor shopping carts with cameras. Amazon's carts show the price of the goods and the total value of the purchase on a display.
To do this, you have to hold the items in front of the shopping cart camera. At the end of the store, the customer can leave the store past the checkouts and the amount will be deducted from their Amazon account. The group wants to stand out with more convenience when shopping. A central idea is to make cash registers unnecessary.
