This is a GNOME Shell Extention that looks for smartcards, and immediately locks the screen if one of them is removed using org.gnome.SettingsDaemon.Smartcard.Token interface.

Since there is no GUI, I can't provide a screenshot! :)

But there's a screenshot of a development release in debug mode which does provide some logging:

• maybe specify which smartcards to look at

• Andy Holmes for very helpful hints and written documentation that allowed someone like me (with pratically zero JavaScript experience) to write a GNOME Shell Extension.
