INFORMATION ENCODED IN A DATABAR CODE 128 BARCODE: DataBar Code 128 barcodes can encode various types of information, including product identification, expiration dates, lot numbers, and serial numbers. Most common uses include encoding product identification information, such as Global Trade Item Number (GTIN), brand name, product description, and packaging type. Expiration dates can be encoded in various formats, while lot numbers identify specific batches of a product, commonly used in industries like pharmaceuticals and food manufacturing. Serial numbers, used in electronics and automotive manufacturing, identify specific units of a product. STRUCTURE OF A DATABAR CODE 128 BARCODE: Barcode is a system of elements, including start code, data characters, check digit, and stop code, which are crucial for accurate decoding of data. Start code is a fixed pattern of bars and spaces, indicating beginning of the barcode. Data characters represent encoded data, which can be numeric, alphanumeric, or special characters. Check digit is a mathematical formula that verifies accuracy of barcode data. It is calculated using an algorithm that varies depending on subset of Code 128 used. Stop code is a fixed pattern of bars and spaces, signalling end of barcode. Minimum and Maximum Size of a Data bar Code 128 Barcode: *Minimum size: Data Bar Code 128 barcode's minimum size depends on the printing method, with the narrowest bar width at least 0.010 inches for direct thermal or thermal transfer printing and 0.007 inches for inkjet or laser printing. Barcode's minimum height is 0.5 inches or 12.7 mm, and may need to be increased for larger data encoded. *Maximum size: DataBar Code 128 barcode's maximum size depends on the label or item, and the scanning equipment used. It should fit comfortably without crowding or overlapping other elements.
