Barcode matching test application: Avoid mix-ups and prove it!
After just a few hours on the job, shipping and logistics operators start to notice that item reference codes are similar. You need to compare barcodes quickly and reliably!
Give your operators mobile verification software: the barcode coder to reduce customer complaints due to product mix-ups. It checks that two, several or a string of codes are identical.
To be installed on a rugged, high-speed, close-reading terminal for production, or a simple smartphone (slow, close-reading). Avoid mixing up parts for shipping. It’s a kind of digital poka-yoke. Option with traceability key = BL or purchase order, and local backup of traces and histories to prove to a customer the one-time correct execution of the control. Multilingual: GB / FR
For all Android systems. Test it!
Meet the need for operational excellence and reduce customer complaints:
you want to install an easy-to-use, visual and audible tool that lets users test the correspondence between two or more complicated or long barcodes printed on a BL (bill of lading), an OF (manufacturing order), a product, a case or a box, and avoid confusing codes and references.
Our application compares linear (1D), QR-code and Datamatrix (2D) barcodes with each other, depending on your barcode reader terminal, enabling factories, warehouses and logistics departments to improve quality testing and reduce delivery errors.
This software can read codes 2 by 2, or even n by n (“n” taking the value you set) or in a row (configurable option), and check that they are identical, displaying the last two and indicating with a green or red color whether their values are identical or not, or whether one of the values in the chain has been different (orange border). In “string” mode, similar to the “n by n” option, the test is carried out continuously: as long as the code is identical to the previous one, it remains green, but warns you as soon as a code is different. This chain mode can be used to test sheets of labels, printed matter or pharmaceutical leaflets.
The truth table is as follows, depending on the options: (1 = positive=green, 0=negative=red, “A”, “B”, “C” are scanned barcodes)
Option in n per n cycle, here n=2

Option in n per n cycle, here n=3

Option in chain

Provide proof of inspection! (optional)
To provide customers with proof that their order has been properly verified, the order code, BL or other key can be entered on a regular basis, or modified on request, before each chain of comparisons (logs of good and bad scans). The trace is dated for each scan, and the history is saved on a local file on the terminal/smartphone, so that it can be extracted and saved in the event of a claim, and thus prove your good faith.
- Streamlined ergonomics
Testing identical barcodes in a chain: green display=identical
- in a single screen, the user simply scans in line: the colored display in the corner of the eye provides information on whether the last two scans match. A different audible alarm is emitted, depending on the case, and is particularly useful for non-matching codes.
Android version in French/English (quick switchover from one to the other).
Likewise no terminal-dependent settings. the barcode reference checker application detects whether you’re using a smartphone with a camera, or a professional terminal with an imager or laser scanner, and adds a button accordingly.
A success rate indicator and the number of comparisons made are also added.
Download the evaluation version of the comparison application, limited to 25 comparisons.

Ruggedized terminals sold :

Palm or pistol format terminal
You can use off-the-shelf smartphones (not sold) with this barcode comparison software, but reading will be slower than with a laser/imager terminal.
Our terminals with integrated barcode scanners increase code comparison speed, thus boosting quality control productivity.
Works on “GMS” (Google Mobile Service) or “non-GMS” terminals (like the “Memor K”).
This kind of application is designed for close reading.
We have several resistant production terminals that we can integrate according to your needs and environments.
Other ideas and requests?
You have other ideas and needs: our company _custom-develops _these kinds of mobile applications for you: ask for a custom scan mobile application design quote: call better than formal.
Other versions of custom concordance tests (on request):
- tailored to your labels (e.g. Galia adaptation to codes that are not quite identical but contain a common root, (prefix /suffix) with several codes to read and compare) barcode comparison for Galia
- adapted to your needs and quality processes: keep track of who scanned it and when for customer proof, read and display product photo on screen etc… with our custom-made authenticity infrastructure
- check for identical symbology,
- with OCR: character recognition, read alphanumeric references that only appear in text.
