It is plenty out there of barcode/QR code scanner apps (both on Android Play Store and Apple AppStore [and iOS 11 include native code scanner in the camera app]) so it may seem there is no need to build a new one but this is not true!

In this blog post I will describe how I built a barcode scanner app (ScannerMApp, currently available in a beta stage on the Play Store) in Delphi using the Edward Spelt’s Delphi port of the ZXing library and my TFrameStand component.
