On April 1st 2020, the Federal Council of Switzerland amended the Ordinance on the Signature Act (VZertES) in one paragraph in connection with the extraordinary situation in the context of the propagation of the Corona virus: https://www.admin.ch/gov/de/start/dokumentation/medienmitteilungen.msg-id-78641.html
This means that during the period of the Corona measures it is possible for the first time that persons can avoid the face2face identification even for signatures not dedicated for contracts of financial intermediaries. You can even be identified by an eIDAS video identification service. The Swisscom Smart Registration Service now enables partners and large customers to offer such identifications. It will start on end of April.
