The test, in brief
FailedThe task could not be completed.
The tested task failed in this session. Read the findings for what happened.
What we tried
Use the GTIN Barcode Generator to generate valid full numeric GTINs with checksums, then verify the result across UPC-A and EAN-13 using known test inputs.
The task outcome is “Failed,” but the source completion label says “Main task completed.” Read this result with that discrepancy in mind.
The positives
What worked well
The tool directory is clearly organized by category, the GTIN form labels the required inputs and output format clearly, and the generated result includes simple Copy and Clear controls.
Worth knowing
What we noticed
The GTIN Barcode Generator calculates incorrect checksum digits for both UPC-A and EAN-13, producing invalid identifiers even though the tool promises valid GTINs with precise checksum calculation.
More detail from the test
After entering a known valid base number and generating a full numeric GTIN, the tool returned the wrong checksum. UPC-A base 03600029145 produced 036000291457 instead of 036000291452. EAN-13 base 003600029145 produced 0036000291453 instead of 0036000291452.
