Please Help! I am using HTML5 QRCode react library for QR code and barcode scanning; and I am working on a tight deadline. I have issue scanning QR codes on small vials. Do we have any fix for this.

  • You could test whether it is the bending of the QR code that is the actual problem. If a flat QR code scans perfectly, but one on a vial doesn't, then it stands to reason the bending is the problem. If it is I doubt there's something you can do about that. – KIKO Software May 26 '22 at 14:47

    You could try to minimize the amount of information to encode and use a normal bar code. Bar codes can be put on a vial without bending their pattern. – KIKO Software May 26 '22 at 14:50
  • @KIKOSoftware Thanks for the quick reply. I tried with an app; and it seems to scan operfectly. But not on the website I am developing to scan the vials. – LearningUser May 26 '22 at 16:11
  • @KIKOSoftware Yes, flat Qr code is getting read properly. Bending is the problem I think. Any way to fix it. It s just a string. I dont have the permission to change the standards. – LearningUser May 26 '22 at 17:28
  • The problem is the algorithm they use to recognize the QR code. Accounting for bending requires a more complex algorithm, which the app clearly uses and your HTML QRcode doesn't. You could look for another QR code scanner and test it. You do have a choice, for instance: https://stackoverflow.com/questions/17652017/read-qrcode-from-a-web-page-with-camera (link is somewhat old, but Google will help you find newer ones). – KIKO Software May 26 '22 at 17:45

The answer is probably a bit late and not necessarily useful, but Denso Wave have developed a type of QR Code specifically for this issue. Unfortunately it has not yet been given an ISO/IEC specification and only proprietary Denso Wave products can create or read iQR codes.

iQR Code with rectangular modules, as well as square ones, can be generated. Thanks to this feature, it is possible to overwrite it with a space where a barcode is and to print it on cylindrical products while maintaining the code's readability, which is difficult with codes made up of square modules.
