You wait in a long queue in the supermarket, but when it’s finally your turn to pay, you can’t find enough money in your purse. 1. While you are bending down to look for them, the people behind you are getting angry. The cashier is pounding her fingers impatiently on the counter.

2. But the good news is: scientists have thought of a way to make queues shorter and paying for things easier. They have invented an eye scanner. In the future, when you pay for food at the supermarket, an eye scanner will take a picture of your eyes and a computer will identify you. 3.

Students at Venerable Bede School, England, have already got an eye scanner in their cafeteria. After the students choose the food they want, the scanner looks for their information and sends a list of the food to their parents. 4.
