Like this, I presume: http://www.secrypt.de/en/products/digiseal-office-pro I believe Germany is about the only country using such schemes. IMO it is based on an altogether weird interpretation and use of the EU signature directive which forces German companies to sign e-invoices as individuals, rather than by a server-hosted "company stamp". This makes the use of batch signatures a necessity for electricity and telecom bills since these are issued in huge volumes. Needless to say Germany is way behind the rest of the world in secure e-invoicing.
