Notes from Dr. Borkosky

GS1-128 barcodes begin with a FNC1 (function one) character to designate them as GS1 System standard-compliant. To generate the check digit for the data as Code 128 B: 1-X7VQBT 1. Each bar or space is 1, 2, 3 or 4 units wide, the sum of the widths of bars must be even (4, 6 or 8 units), the sum of the widths of the spaces must be odd (3, 5 or 7 units), and total 11 units per symbol.

They can be printed with or without human-readable characters. Exactly which character set is determined by the specific Code 128 codeset being used.

Code set A includes lots of non-typeable control codes in it.

Optimizing the length of the resulting barcode is important when barcode readers are used which must detect the entire barcode image at once in order to read it, such as common laser scanners. It tells me something is missing in the algorithm of the check-digit calculations I found on this web site.

What language are you writing your program in?

For the beginning and ending part of the string, switching to code set C is not effective. The barcode is separated into five data sources, so I'm not sure how that would work.

Code 128 is a very effective, high-density …

There will always be 6 runs and the lengths of these 6 runs form the Widths value. // -->

Code 128 barcodes can't be made 'by hand': you'll need barcode software, or Code 128 barcode functionality in a larger program, to create one. // -->.

Create a blank text field in your Word document where you want the barcode to be. 104 + (17 x 1) + (13 x 2) + (56 x 3) + (23 x 4) + (54 x 5) + (49 x 6) + I'm working in Bartender 10 and I'm trying to create a 7 digit barcode with a check digit at the end, that would appear both in a scan and in the human readable (For example it would be 1486179X, X being the check digit).

Codeset B barcodes are used for alphanumeric data including both uppercase letters/capital leters and lowercase letters, as well as the numbers 0-9, and punctuation marks.

Check digit calculation for the above Zip code example: For the end user, Code 128 barcodes may be generated by either an outside application to create an image of the barcode, or by a font-based barcode solution. The stop pattern permits bidirectional scanning. (If the following symbol is a shift, then a second symbol will be used to obtain the character.)
