Section 1
A Cashier Made of Cameras
At lots of grocery stores now, you can scan your own things and pay. Above the machine, a little camera is watching. That camera has AI inside.
It checks that the apple you put on the scanner is actually an apple, not a much more expensive avocado. It also notices when something gets bagged without being scanned.
What the camera does
- Looks at the shape and color of fruit
- Watches for things that go in the bag without a beep
- Shows the worker if something looks off
Key terms in this lesson
The big idea: the robot cashier is a camera with a fruit-and-veggie brain. It speeds up shopping but a real worker is still nearby.
