Have you ever wondered what does the barcode on product labels mean? Do you know how to read a barcode?
While we can always leave it to the barcode scanners to check the price of a product in the supermarket, knowing how to read barcode while shopping for groceries can actually be fun and educational. And you can use this skill to impress your friends. Haha!
If you want to learn how to read barcodes, i.e. how numbers are derived from a series of thin and thick whie and black lines, you can read this article “Read 12 digit UPC barcodes” on Wikihow.
There is a rumour saying that the first three digits of any UPC barcode represents the country where the item was made. Apparently this is not true. So, what do the numbers on a barcode really mean? You can find out the answers here.
Now, I’m going to immerse myself in the world of black and white lines…
