Hi Nigel "So you were able to resolve it." No. Maybe I didn't put it right. So. If we use some online service to generate QR Code, then all is OK. Online service generate QR Code with utf-8 encoding. The IEVision library recognizes the code completely. But we're using a ready-made stamp for QR-Code. We do not know what kind of encoding is used of the stamp. And the IEVision library does not recognize this QR-Code completely.
„What version of Delphi are you using?“ We're using Delphi 10.4.
