Swisscom Signing Service

The Swisscom Signing Service is a cloud service for electronic signatures and timestamps for documents and files. It is offered as Swiss managed service to service providers, public authorities and companies.

The signing service allows documents and files to be signed in a legally compliant manner in the scope of the eIDAS (EU) regulation and the Swiss Signature Law (ZertES). Electronic signatures ensure the integrity and/or authenticity of such files for the relevant contract partner or legislator.

Combined with Swiss SIM based Mobile ID, international Mobile ID App from the Google/iOS Store or a combination of password and one-time-code via SMS, the KPMG-audited Signing Service enables binding signatures to be authorized by mobile phones. You also benefit from the expertise of Swisscom as a legally recognised certificate service provider (CSP) in Switzerland and Austria.
