Check Digit Calculation Step 1: Starting with the the 1st data character, number each characters position.The sample driver does not require any barcode scanner hardware to function because it operates on a software device.

Or ‘B’ before the non-numeric character using guidelines 1(b) and 1(c) above to chooseīetween code ‘A’ and code ‘B’. (b) Otherwise insert code ‘B’ before the lower case character.Ħ. When in character set ‘C’ and a non-numeric character occurs in the data insert code ‘A’ (a) If following the lower case character there is a control character before another lowerĬase character, insert the shift character before the lower case character. (b) Otherwise insert code ‘A’ before the control character.ĥ. When in character set ‘A’ and a lower case character appears in the data: (a) If following the control character there is a lower case character before anotherĬontrol character appears insert the shift character before the control character. (b) If there is an odd number of digits in the group insert code ‘C’ immediately after theĤ. When in character set ‘B’ and a control character appears in the data: (a) If there is an even number of digits in the group insert code ‘C’ before the first digit. Or code ‘B’ before the last digit, using guidelines 1(b) and 1(c) above to choose betweenģ. If four or more digits occur together when in character sets ‘A’ or ‘B’: (b) Otherwise, if a control character occurs in the data before any lower case characterĢ. If start character ‘C’ is used and an odd number of digits begin the data, insert code ‘A’ (a) If the data begins with four or more digits use start character ‘C’. NOTE: The Bars & Stripes barcode software automatically choose the correct START, CODE, and SHIFT characters in accordance with the following guidelines. The following guidance should be followed to minimize the symbol length. Guidance on the use of START, CODE and SHIFT characters The Code 128 specification allows for Human readable information to be printed anywhere outside of the symbol area. The first column in the table, ‘The Value’, is the value used to calculate the check digit. Notice that the sum of the barwidths in any character is always even, and the sum of the space widths is odd. The table holds the bar/space widths for all the Code 128 character set. The narrowest possible bar or space will thus be one quarter the width of the widest. (The stop character has six bars and five spaces as the final symbol will always have one fewer space than bars.)Įach bar or space can be one of four different unit widths. The quiet zone should be at least ten times the width of the narrowest bar/space element.Įach character in the barcode symbol is composed of six bars and six spaces.

A quiet zone or white space to the right of the bars.A quiet zone, or white space to the left of the bars.The barcode symbol structure consists of: The Code 128 Specification requires the inclusion of a check digit. Each code set has one or more characters reserved for special functions. If the data consists only of numeric data then Code Set C provides twice the packing density of Code Sets A and B. Special ‘shift’ characters in each Code Set enable an alternative Code Set to be substituted during the scanning process. Any of these codes may be selected by appropriate selection of start character. It also is considered the most easily read barcode with the highest message integrity.Ĭode 128 has three different character sets defined in the table below as Code Set A, Code Set B and Code Set C. Code 128, so called because it can encode all 128 ASCII characters, is the preferred symbology for many barcode applications.
