Barcodes usually comprise a series of black and white lines along with numbers beneath. To read barcode numbers manually, start with the first digit on the left, known as the system digit, which signifies the type of product. Next, identify the manufacturer code (the next 5 numbers), followed by the product code (the subsequent 5 numbers). Finally, the last digit is the check digit, used for error detection. This format enables easy product identification and inventory management.
