About Linear Barcodes

Linear barcodes, also known as 1D barcodes, are the traditional barcode format consisting of parallel lines of varying widths and spacing. They are widely used in retail, inventory management, and logistics. Code 128 is one of the most versatile linear barcodes, capable of encoding all 128 ASCII characters. Code 39 is another popular format that can encode alphanumeric characters. UPC and EAN barcodes are specifically designed for retail product identification and are required by most retailers worldwide.
