Issue: The higher the QR code version, the more data modules there are and the more challenging it is to read such dense QR codes.
Solution:
Dynamsoft Barcode Reader uses a special algorithm optimized for reading a dense QR code. Set the appropriate ScaleUpModes, which determines the process for scaling up an image for detecting barcodes with a small module size.
