FAQs About Code 128
1. What is the difference between Code 128 and other barcode types?
Code 128 barcodes stand out from other barcode types primarily due to their exceptional versatility and data density.
These barcodes can encode all 128 ASCII characters, including control and printable characters, allowing them to hold more information in a smaller space than many other types, such as Code 39 or UPC.
2. What does 128 mean in Code 128?
The "128" in Code 128 refers to the barcode's ability to encode all 128 ASCII characters. This includes a wide range of symbols, numbers, and letters (both upper and lower case), making it one of the most flexible and capable barcode symbologies.
3. What is Code 128 barcode validation?
Code 128 barcode validation is a crucial process that ensures barcodes are properly formatted and readable under standard conditions. This validation checks that the barcode adheres to specific technical standards such as dimensions, contrast, quiet zones, and reflectance, which are essential for readability by scanners.
