As the text length increases further, these barcodes become noticeably unwieldy and machines might have difficulty scanning them. One-dimensional barcodes are suitable for conveying text data up to about 30 characters long, generally speaking. Either way, the check digit cannot be used to store extra useful information, because its value is determined by all the preceding digits. Thus for convenience, you should use the program to automatically compute the check digit. If you create the barcode in raw mode you can set the check digit to any value – but scanners will ignore barcodes with an incorrect check digit. The UPC and EAN schemes show the trailing check digit to the human. You can save the generated barcode image by right-clicking on it. Note that some schemes have limitations, such as only encoding numbers, supporting a limited character set, and/or restricting lengths.
