misdetection in reading qRcode

[mipstux]

Hello,
In France it is possible to send letters using stamps with a qRcode allowing the letter to be tracked. But I noticed that on my sending yesterday barcode misdetected the qrcode and generated an error on the last digit of the character string. I kept an image of this qrCode via the application but the green crosses at each end prevent me from scanning the qrCode again. But when I dropped off my letter at the Post Office, I asked the employee to scan the qRcode. It came out correctly.
You can see at the end that BarCode read ...479333 or it is a .....479337. 0r you have an extra 3 :-(
(sorry, my english is note very fluent and i used a translation tool. Also, i'm not a developper and my experience in github is very recent)
Thanks a lot

That's an interesting case. So far two barcode readers that I found for Android produced the same result as mine, i.e. with ...479333... I'll try to debug this issue when I have time. And thanks for reporting it!

and btw it's not a QR-code it's DataMatrix 🙂

So far I haven't been able to find a decoder, online or offline, which would produce a result different from mine 😐️
Maybe it is correct, after all🤔
