An example of using Qt to develop an ID card reader on a Linux system, followed by the C++ demo source code:
Compilation platform:
Kirin V10 (SP1), amd architecture, Intel i7-10700 CPU
Qt version:
Qt Creator 4.11.0, Based on Qt 5.12.12 (GCC 9.3.0, 64bit)
donseeTest: project source code
build-donseeTest-unknown-Release:Release
build-donseeTest-unknown-Debug: Debug
Double-click donseeTest in the Release or Debug folder to run the test.
The card reader USB interface supports driver-free models such as Guangdong Eastcom ID card reader EST-100, EST-J13X, EST-100M (HID).
For other platforms, please replace the following 2 library files and recompile.
libdonsee.so
