Barcode comparison & matching test scanner: Avoid mix-ups and prouve it !

A barcode poka yoke

The item reference codes are similar to the eye of the shipping and logistics operators after a few hours of work: mixtures of parts are shipped to customers? The barcodes must be compared quickly and with certainty!

Give a mobile verification software to your operators: the barcode decipherer to reduce your customer complaints by product confusion.
It tests that two, several or a chain of codes are identical.
To be installed on a resistant and fast terminal for production or a simple smartphone (slow reading). Avoid mixing up parts during shipping. It is a kind of digital poka-yoke.
Option with traceability key = BL or purchase order, and local trace backup,logs, history to prove to a customer the unique good execution of the control. Multilingual: GB / FR

For all mobile on Android. Test it!

Meeting the need for operational excellence and reducing customer complaints :

You wish to install a means easy to use, visual and sound, which allows the user to test the correspondence between two or more complicated or long codes, printed in barcode on a BL (bill of lading), on an OF (order of manufacture), on a product, a case, a box and avoid the confusions of codes and references.

Our application compares, according to your barcode reader terminal, the linear barcodes (1D) or QR-code, Datamatrix (2D) between them and allows the factory, the warehouse, the logistics, to improve its quality tests and to decrease its delivery errors.

This software allows to 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, to display the last two and to say by a green or red color if their values are identical or not, or if one of the values of the chain was different (orange border). In "string" mode, similar to the "n by n" option, the test is done in a continuous way: as long as the code is identical to the previous one, it remains green but warns as soon as a code is different. This chain mode allows to test label or printed sheets, pharmaceutical leaflets.

The truth table is the following according to the options :
(1 = positive=green, 0=negative=red, "A", "B", "C" are scanned barcodes)

Option in cycle n by n, here n=2 :

Code entry A A B A A A
Comparison result:1 out of 2 times 1 0 1
Reset auto, after comparison yes yes yes

Option cycle n by n, here n=3 :

Code entry A A A B A A
Comparison result:1 out of 2 1 1 0 1
Reset auto, after comparison yes yes

Chain option :

Code entry A A B A A A
Comparison result, at each input 1 0 0 1 1
Reset at start yes

Bring proof of completion of the check! (option)

In order to bring to a customer the proof of the good realization of the verification of his order, in option, the order code, BL or other key can be seized in a regular way or modifiable on request before each chain of comparisons (logs of the good and bad scans). The trace is dated at each scan and the history is saved on a local file on the terminal / smartphone in order to be able to extract and save it in case of claim and thus prove your good faith.

Ergonomics is streamlined: in a single screen, the user only has to scan in line: the display in the corner of the eye informs the user of the correspondence of his last two scans. A different audible alarm is emitted depending on the case and is particularly interesting for non-corresponding codes.

Single version in French - English (quick switch from one to the other).

Similarly no settings: the barcode reference match verification application detects whether you are using a smartphone with a camera or a professional terminal with an imager or laser scanner and adds a button or not to the function.

An indicator of the success rate and the number of comparisons made is also added.

How to install our applications

Hardened terminals sold :

Terminal de scan en ergonomie palm ou gun
Scanning terminal in palm or gun form
4.3" touch screen, gun mode scanning (imager), induction charging (no contacts), Android

You can use commercially available smartphones (not sold) with this barcode comparison software, the reading will be slower than a terminal with a laser.
Our terminals with an integrated barcode reader allow you to multiply the speed of code comparison by about 100 and thus increase the productivity of quality control.

We have several rugged production terminals that we integrate according to your needs and environments: Our mobile software and harwares

Works on "non-GMS" terminals (such as the "Memor K")

Screen copies : simple ergonomics : see portfolio

Other ideas and requests?

You have other ideas and needs: our company develops to measure this kind of mobile applications for you: ask for a quote for designing a custom mobile scanning application (contact form or of dowloading).

Other versions of customised matching tests (on quotation):

  • adapted to your labels (for example type Galia with several codes to read and compare)
  • adapted to your needs and quality process: keep the traceability of who scanned it and when for proof to the customer, reading and displaying a picture of the product on screen etc... with our custom-made authenticity infrastructure
  • adapt to codes that are not quite identical but contain a common root (prefix /suffix),
  • verify the identical symbology used,
  • with OCR: character recognition, read alphanumeric references, which only appear in text.
