About Barcode Formats

Barcodes encode data as a pattern of parallel bars that can be read by laser or camera scanners. Retail products almost always use EAN-13 (worldwide) or UPC-A (US/Canada), each with a built-in check digit for accuracy. CODE128 and CODE39 are common in logistics and internal stock control because they can encode letters as well as numbers.
