We have a web application which requires bio-metric authentication for users to login to the web application. Currently those users cannot login from Android devices because they cannot verify bio-metrics on their smart phones. We want to find a solution which will help our web application running on an Android device to authenticate our users using bio-metric device which will be connected using OTG cable.
We are currently using Java Applet for bio-metric verification on our desktop applications. We know so far that we cannot open Java Applets on Android devices. So we will be willing to find another solution which will help us perform bio-metric authentication on both our desktop and Android devices.
