Verification ≠ Validation Verification : Determining the quality of printing/marking to predict readability • Checking code quality to an ISO standard to ensure that it can be read by any reader. • Requires a “precision test instrument” (Verifier) that is certified to conform to a specific ISO standard • Produces a barcode grading report and typically includes advanced diagnostics tools for printing/marking process troubleshooting. Validation :
Checking the content of the code • Checking that a code can be read now by a particular reader and confirms that the decoded data output is what was expected • Confirms that the data content and syntax are what was expected and/or dictated by standards/specs • Does not provide a reference point on whether another reader should be able to read the code • Does not meet requirements for “ISO Grading” found in many specs
