How barcodes work
Barcodes encode data using parallel lines of varying widths and spacing. Barcode scanners use laser or camera technology to read these patterns and decode the information.
Code128 is the most versatile format, supporting all ASCII characters. EAN-13 and UPC-A are standard for retail products.
