How is the Code 11 Barcode unique from other barcodes? There are multiple ways in which the barcode symbology of Code 11 differs from other barcode variants. The key distinctions between Code 11 and other widely used barcode types will be covered in this section. •Other barcode varieties, such as Code 128 and QR codes, may encode alphanumeric letters and even binary data; in contrast, Code 11 can only encode numeric digits and the hyphen. For applications that need to encode a little quantity of data, Code 11 is perfect; however, it might not be appropriate for applications requiring a larger amount of data to be encoded. •Code 11 has an integrated check digit to guarantee the correctness of the encoded data. A unique technique that considers the values of the encoded characters is used to calculate this check digit. There are check digits in other barcode types as well, such as UPC and EAN, however the algorithm used to determine the check digit is different. •code 11 barcodes are usually larger because they have a lesser data density than other barcode variants. For situations when there is a shortage of space, as on little products or in tight packaging, they might not be appropriate. •There are several ways to print Code 11, including thermal transfer, laser printing, and inkjet printing. To ensure accurate scanning, however, certain considerations throughout the printing process can be necessary. Code-11 Barcode Structure- •The barcode segment containing the information being encoded is called the data field. •A unique character called the "check digit" is used to guarantee that the data has been encoded accurately. The final character of a barcode is always the check digit. •The start character of the Code 11 barcode is represented by the number "110". To alert the barcode reader that a Code 11 barcode is being scanned, follow these steps. •The end character is represented by the sequence "110".
