MatchBenchBY SMARTFACTFREE BARCODE COMPARISON
Scan a master label once, then scan each label in the run against it. MatchBench records every comparison, keeps the reference fixed until you change it and gives you a CSV and PDF record of the run.
Free to use. No account, email address or trial. Works offline once prepared.

Illustrative values, not a real comparison. A match compares decoded values; it does not approve a label.
For packing bench leaders and quality staff who sample or check a run of printed labels against an approved master label or job reference.
A USEFUL STARTING POINT
When labels are checked against a master, the reference must not drift. In MatchBench the reference stays fixed until you deliberately set a new one. A new reference starts a new group, and earlier comparisons stay with the reference they were checked against, so the record of the run is never rewritten.
FROM QUESTION TO EVIDENCE
Scan the master label or job reference. It is shown as the reference group, with its value and how it was entered.
Scan each label in turn. A barcode held in front of the camera counts once, so take it out of view before scanning the next label. A keyboard scanner records one comparison per scan.
The list shows the number of observations, exact matches and different values. Download a CSV with exact values, or an A4 PDF report listing every reference group and comparison.
A packer scans the master label P-20418-BLK, then 24 carton labels from the run. MatchBench shows 24 observations, 23 exact matches and 1 different value: P-20418-BRN, first difference at character 10. The PDF report lists every comparison with its source and time for the shift lead to review.
USED IN PRODUCTION
MatchBench compares the values you scan, one label at a time. Two SmartFACT services work earlier in the job: choosing the right label data before it prints, and checking that the right components go into each kit. Both are in early access, with scope agreed at onboarding.
Early accessChecking a printed label against its reference finds a wrong value after it is printed. LabelRules works before printing: describe label rules in plain English, and approved rules select each job's layout, resolve customer codes and check required values before the label prints. LabelRules Free prints at an attended workstation; Pro adds connected triggers, routing and unattended printing.
Early accessMatchBench compares one value with one reference. When a kit needs the right components in the right quantities, KitProof turns approved plain English component rules into each kit's expected parts and quantities, then checks every scan against that plan before the kit leaves the bench.
BEFORE YOU START
Yes. Scan or enter a new reference, or choose Use as a manual reference on any comparison in the list. Either starts a new reference group. Earlier comparisons stay with their original reference, and a copied reference is recorded as manual.
No. It records which values were compared, with their entry source and the time on this device. It does not show that the master is correct, that each scan was a different physical label or that the barcodes are well printed. It is a local record, not a signed approval.
A project holds up to 10,000 comparisons and 1,000 references, within 5 MiB of data. The PDF report is limited to 200 pages. If a report would be longer, MatchBench says so, and the CSV and project backup still contain everything.
MatchBench compares decoded text exactly. A match shows that two values are identical. It does not show that the reference is correct, that two different labels were scanned, what a carton contains or how well a barcode is printed: it is not a barcode verifier, and it does not interpret GS1 data. There is no list of expected pairs, no shared record and no sign-off, and one person works on one device. Each value can be up to 4,096 characters, with up to 10,000 comparisons, 1,000 references and 5 MiB of data in a project, and PDF reports up to 200 pages. The camera reads Code 128, QR Code, Data Matrix, EAN-13, EAN-8, UPC-A and UPC-E.
Your comparisons stay in this browser. They are kept in memory while the tab is open, or in this browser between visits if you choose Save on this device. The camera starts only when you open it, and images are decoded on your device, never stored or uploaded. Nothing you scan is uploaded, and no account or contact details are needed. Google Analytics is optional and loads only after you accept; it never receives barcode values, results or file contents.
