Why Code Checks Are Important

Have you ever had to wait longer than usual in a supermarket line because a barcode couldn't be scanned at the checkout?

For this reason, vision inspection systems are designed to reject products with poorly printed or unreadable codes from the production line before they even reach the market.

But how does barcode checking actually work and why is it so important?
