What are one-dimensional barcodes?

A one-dimensional barcode is like a special line on a shopping item that tells the store what it is.

Imagine you have a toy box full of different toys, cars, blocks, and balls. Each toy has a label with numbers or letters so the store knows which one it is. A one-dimensional barcode works in the same way, but instead of letters and numbers, it uses black and white lines.

These lines are like a secret message that a scanner can read. When you take your toy to the checkout, the clerk scans the barcode with a little machine, and poof, the store knows which toy it is and how much it costs!

Think of it like a staircase: each step has a certain height, and together they make a pattern. The one-dimensional barcode has lines that are wide or narrow, and together they make a pattern that tells the story of the item.

The next time you see a label on a snack or a book, try looking closely, there might be one of these special line patterns hiding right under your nose!
