Verification vs. Validation • Verify: Check a code’s quality to an ISO standard (ISO 15415 or ISO 15416) to ensure that it can be read at any point on the line, by any reader. є Requires a “precision test instrument” (verifier) that is certified to conform to a specific ISO standard, ISO 15426 є Produces a barcode grading report and typically includes advanced diagnostics tools for barcode defect troublleshooting • Validate: Check that a code can be read right now by a particular reader.
є Doesn’t provide a reference point on whether another barcode reader should be able to read the code є Does not check whether the barcode size and data structure complies with standards such as GS1 є Does not meet requirements for “ISO Grading” found in many specs
