FREE BARCODE COMPARISON
Two labels. Is it the same value?
Scan a reference barcode and the label you want to check, and see whether the decoded values are identical. Use the phone camera, a keyboard scanner or typed entry, with no app to install and no account.
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.
MADE FOR THE FLOORFor stores, despatch and production staff who reprint or replace a label and need to check that it carries the same value as the original, the traveller or the paperwork.
A USEFUL STARTING POINT
A replacement label has to say exactly what the original said
When a label is damaged, reprinted or copied onto paperwork, its value has to stay exactly the same. Reading two long codes by eye is slow and easy to get wrong. MatchBench decodes both, compares them character by character and tells you whether they are identical or where they first differ.
FROM QUESTION TO EVIDENCE
Three steps to a useful result.
- 01
Scan the original
Scan the barcode on the original label, traveller or instruction sheet as the reference. On a busy label, hold only the barcode you mean inside the camera's guide box.
- 02
Scan the replacement
Scan the new label in the Barcode to compare field. With the camera, close the camera view after the read to see the result.
- 03
Read the answer
Exact match means the decoded values are identical. Different value shows the label's value and the position of the first character that differs, with nothing changed or corrected.
A CONCRETE EXAMPLEOne character, found without reading by eye
A carton label for work order WO-24817-03 is damaged and reprinted. The reference scan from the traveller reads WO-24817-03 and the reprinted label reads WO-24817-08. MatchBench reports Different value, first difference at character 11, and keeps both values in the comparison list and the PDF report.
USED IN PRODUCTION
When label checks are part of every job.
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.
LabelRules
Checking 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.
KitProof
MatchBench 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
A few practical answers.
Which barcodes can the camera read?
Code 128, QR Code, Data Matrix, EAN-13, EAN-8, UPC-A and UPC-E. Decoding happens on your device, using the browser's own barcode reader where it has one and a decoder supplied with the tool otherwise. For any other symbology, use a keyboard scanner or type the value.
Do I need to install an app?
No. MatchBench runs in the browser. The camera button appears when the browser can use a camera on this site, and the browser asks for your permission the first time.
What if the label has more than one barcode?
The camera decodes only inside the guide box and accepts a value once it has read the same value twice in a row. Hold the barcode you mean inside the box, then check the recorded value on screen before you rely on the result.
What are the current limits?
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.
What happens to my data?
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. Change your choice with Analytics settings on these pages or Change preference in the tool; see /privacy/.
