Add support for CNK codes #493

Open thibaultmol opened 1 month ago

thibaultmol commented 1 month ago

In Belgium pretty much all products sold in pharmacies use a CNK code which is a specific MSI coded barcode: https://www.apb.be/SiteCollectionDocuments/ALL%20PARTNERS%20ACCESS%20DOC/CODES-CNK-DOC/BROCHURE-CNK-EN.pdf

see example: Screenshot 2024-09-18 at 23-07-46 Sharp Scan - thibaultmolleman@apotheekmollemandecoster be - Apotheek Molleman De Coster Mail

Most of them use this CNK code. Others (that have unique codes for getting money back from health insurance have datamatrix codes which already work properly) and a smaller number of products use regular EAN codes which also work.

Thank you for bringing this up! I've never seen these barcodes, unfortunately. Very interesting! And sorry for the slow response 🙈

Now, this barcode format would have to be added to ZXingCpp (that's the library this app uses to read barcodes). @axxel Do you know CNK codes?

No, I haven't seen these before. The link to the PDF seems broken. @thibaultmol can you double check that?

I see. They use "just" a fixed length MSI code. That symbology is pretty simple in its construction. I guess this could be implemented along the lines of the existing Code39 reader.

That said, I don't have spare time to put into this right now. But if there is a business interest (money involved), my priorities can be influenced :). In that case, please get in touch via zxingcpp at gmail dot com.
