How to integrate Zapper plugin with EasySocial registration and connection page ?

Hi.
This plugin enables the Scan to login authentification workflow. It displays a QR Code from Zapper technology next to Regsitration and Connexion pages. But it seems to only works with COM USER Registration not EasySocial.

Link 1 : Title
Link 2 (demo) : Title

I would like to duplicate the plugin and change some codes to make it works with easy social but i'm not good at PHP...

Any help ?
