Is Universal Smartcard Browser Gateway safe?

Clean risk

Enables supported web applications to access a connected smartcard through a native messaging host.

This add-on works with a companion application installed on the computer; without both parts, the web applications cannot access the smartcard. The store description says smartcard access is limited to allowed domains including telesec.de, wcos.de, and magenta-security-sign.com.
