 Invoke <code>setup-browser-eid</code> to configure (and whenever this gets garbage-collected), and restart your browser.
+== Belgian eID cards ==
+The Web eID browser extension, used for authentication with Belgian eID cards, requires the PKCS#11 module <code>libbeidpkcs11.so.0</code> to be available in the directory <code>/usr/lib/x86_64-linux-gnu/</code>. Since this directory does not exist by default on NixOS, the Web eID application installed on the host system will not detect or support Belgian eID cards.
+To resolve this, you can create a symlink from the Nix store version of <code>beidpkcs11.so</code>, provided by the <code>eid-mw</code> package, into <code>/usr/lib/x86_64-linux-gnu/</code>:<syntaxhighlight lang="nix">system.activationScripts.web-eid-app = {
+  text = ''
+    mkdir -p /usr/lib/x86_64-linux-gnu
+    ln -sf ${pkgs.eid-mw}/lib/pkcs11/beidpkcs11.so /usr/lib/x86_64-linux-gnu/libbeidpkcs11.so.0
+  '';
+};</syntaxhighlight>This script ensures the required symlink is created at system activation time and remains up to date with the correct Nix store path for <code>eid-mw</code>.
