Pyinstaller with nfcpy

This forum has been a massive help for me in the past.

I have been using PyInstaller with some success to move python application to non-development machines.

However, recently the application has started using nfcpy.

I am finding the installed application errors/exception with 'no module named pn533'. This is coming from nfc.contactlessfrontend('usb'). I have a SCL3711 usb dongle which has the pn533 chipset I believe.

So the error is clear to me, that PyInstaller whilst it has identified the nfcpy module is required it hasn't included the imports for at least pn533 but maybe other components of clf.

Has anyone had any success with using PyInstaller with nfcpy?

I have tried to add 'pn533' has a hidden import but PyInstaller can't find it - presumbly its not really a module like nfcpy is.

Maybe there is another one to include support - like moving the pyc, however, that didn't work for me.

Many thanks in advance for any thoughts you may have.
