This website to demonstrates the viability of using your NFC-enabled ID-card and your smartphone to authenticate yourself. This is a proof of concept solution, so currently only authentication is supported. This solution was created for Software Project (Tarkvaraprojekt) course in the University of Tartu in cooperation with Martin Paljak.
This solution is meant to be web-eid.js compatible, so this example website uses a fork of web-eid.js which supports the Android authentication app.
To get started, download and install the authentication Android app from GitHub (Android 8.0+ required). You can then click "Login" to authenticate yourself on this demo website with the app or if you are using a non-Android device, you can use both the app or the default web-eid.js option to login using the smartcard reader.
