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.

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.
