Hi
Hello
I have issue with barcode on LazReport.
I have Ean13 barcode on the report.
In many cases I send some 13 digits to generate the code but on report I get different one.
For example
2023001004144
Generates
2023001004141
There is a checksum check box in the bar code options, if I check this out the number(human readable code is correct), but the barcode read by reader is tootaly wrong.
Anyone faced suchj issue??
Thaddy:
No.
And I see no code at all....

You don't have issue with Lazreport, but with your EAN13 code.
Last digit in EAN13 is checksum: EAN13 consists of 12 digits + checksum digit. So for code 202300100414 check digit is 1.

Thank, yes I did some reading on EAN 13, we changed the logic to 12 digits.
