What is Code 128 barcode & what are its specifications
Code 128 is a high-density linear barcode symbology defined in the ISO/IEC 15417:2007 standard, used for encoding alphanumeric or numeric-only barcodes. It is widely used in various industries, including shipping, logistics, healthcare and retail, among others. The Code 128 barcode symbology is characterized by its high density and fast scanning capabilities, making it an ideal solution for businesses that need to store and retrieve information quickly and efficiently.
Code 128 is capable of encoding all 128 ASCII characters, making it suitable for encoding alphanumeric data. This includes letters, numbers, and various symbols. Additionally, the barcode symbology can also be used to encode numeric-only data, making it ideal for use in applications that require fast scanning of large amounts of numerical data, such as tracking numbers for packages or invoices.
One of the main advantages of Code 128 is its ability to store a large amount of information in a compact space. This makes it ideal for use in applications where space is limited, such as product labeling or document tracking. Code 128 barcodes are also highly dense, meaning that they contain a large amount of information in a small area. This results in a significant increase in scanning speed, making it possible to quickly retrieve information from a barcode.
Another advantage of Code 128 is its versatility. This barcode symbology can be used in a variety of applications, including product labeling, document tracking, and inventory management. It is also compatible with a wide range of barcode scanners, making it easy for businesses to implement the technology without having to purchase new hardware.
Code 128 is also a highly secure barcode symbology. The barcode includes a check digit, which is used to validate the accuracy of the encoded data. This helps to ensure that the barcode is read correctly and that the information contained within it is accurate. Additionally, the barcode symbology supports error correction, which allows for the correction of minor errors that may occur during scanning, such as smudging or wear and tear of the barcode.
In conclusion, Code 128 is a high-density linear barcode symbology that is widely used in various industries for encoding alphanumeric or numeric-only barcodes. It is characterized by its fast scanning capabilities, high density, versatility, and security features, making it an ideal solution for businesses that need to store and retrieve information quickly and efficiently. Whether it's for product labeling, document tracking, or inventory management, Code 128 provides businesses with a reliable and efficient barcode solution that meets their needs.
Code 128 Features
- Widely implemented in many applications because of its excellent density and large selection of characters.
- Provides the highest numeric-only data density.
- The character sets include the digits (0-9), both uppercase and lowercase letters, and all standard ASCII symbols and control codes.
- Variable length symbology with characters that consist of 3 bars and 3 spaces such that the total character width is 11 modules.
- The symbology includes a checksum digit for verification, which is calculated using a module 103 scheme.
