Several standards of Code 128 may require a MOD10 Check Character (Digit) calculation. Some of these standards include GS1-128, SSCC-18, and SCC-14.
When calculating a MOD10 for Code 128, the AI (Application Identifier) is not part of the calculation. Let's use an SSCC18 value as an example:
The (00) is the AI character and will not be part of the MOD10 calculation. However, the remaining data, 00801234999999999, will.
When the ApplyTilde option is enabled, some IDAutomation products will allow the user to encode FNC for AIs using the parentheses. If your product does not have this feature, then encode the FNC using the Tilde Method
To calculate the MOD10, ApplyTilde must be enabled.
Let's encode and calculate the check digit for the value above using the Tilde method.
The ~212 identifies the two digit AI. For three digits use ~213, four digits use ~214, etc.
The ~m17 looks at the remaining data that is not an AI, and calculates the check digit.
Using the Parentheses method is very similar:
The check digit is 7.
The scanned result is 00008012349999999997
How do I know what to set ~m to?
You must refer to the standard that you are required to generate.
