Frequently Asked Questions
What is a barcode?
A barcode is a visual, machine-readable representation of data. It typically consists of parallel lines (bars) and spaces of varying widths that encode information.
Why are barcodes used?
Barcodes are used to quickly and accurately identify products, track inventory, manage assets, and streamline checkout processes in retail, logistics, and many other industries.
What are common barcode types?
Common types include EAN-13 (for retail products globally), UPC-A (for retail products in North America), and Code128 (for logistics, shipping, and alphanumeric data).
How do barcode scanners read barcodes?
Barcode scanners use a light source and a sensor to detect the light reflected from the bars and spaces. This pattern is then converted into electrical signals and decoded into the original data.
Can I generate barcodes for free online?
Yes, many online tools allow you to generate standard barcodes like EAN-13, UPC-A, and Code128 for free, often for personal or small business use.
What's the difference between EAN-13 and UPC-A barcodes?
EAN-13 is a 13-digit global standard, while UPC-A is a 12-digit standard primarily used in North America. EAN-13 is a superset of UPC-A.
What is Code128 best suited for?
Code128 is a high-density alphanumeric barcode ideal for logistics, shipping labels, and internal tracking systems due to its ability to encode a wide range of characters.
