Signing without pen and paper: The qualified electronic signature (QES) replaces handwritten signatures in the digital world. This allows you to sign documents around the clock on the web – conveniently on your computer or on your mobile phone with a scanning function. It is a server-based remote signature solution provided by Swisscom. It enables persons and companies to validly conclude online business processes with the help of electronic signatures and seals. The advantages of electronic signatures are efficient digital processes without media discontinuity, no paper consumption, as well as cost and time savings.
A qualified electronic signature (QES) is equivalent to a handwritten signature under Swiss law and is valid throughout the entire Swiss legal area. This enables you to electronically sign in a legally valid manner all documents that you have previously signed manually (simple written form). If you want to sign a document for the European legal area, select our QES according to the European Signature Standard (eIDAS).
Administrative processes become much simpler, faster and more secure. This is because an electronic signature not only reduces costly business processes and saves resources in terms of transport and paper, but also protects the signed document against tampering and is thus a trustworthy alternative to a handwritten signature.
Before using Swisscom Sign, you must identify yourself once.
The qualified electronic signature (QES) is governed in Switzerland by the Swiss Federal Act on Electronic Signatures (ESigA).
A document cannot be signed through several different signature providers at the same time.
The qualified electronic signature (QES) is legally equivalent to a handwritten signature and meets the highest security standards.

You can invite someone to sign a document together with you.
Here’s how it works:
To withdraw an invitation, you can click the "Finish Signing Process" button. This will interrupt the process so that signatures can no longer be added to the document.
If you have received an invitation to sign a document but do not want to sign it, you can simply ignore the email. There is no specific function for rejecting a signature invitation.
Click on the “Download” button. All signed documents are available for download for 30 days.
All documents are permanently deleted after a period of 30 days.
Your signed documents are automatically deleted upon completion of the signing process (i.e. after 30 days). Therefore, download the document beforehand to save it as you wish. If you have been invited to sign the document, you can download the signed document again within 30 days. To do so, please click on the link sent to you by email.
To see the status of a signing process, click on the link you received via email at the start of the signing process. Now look at the top right to see if all people have already signed.
Your signed documents are automatically deleted upon completion of the signing process (i.e. after 30 days). Therefore, download the document beforehand to save it as you wish.
Once you have sent an invitation to sign, it can no longer be edited afterwards. However, you can terminate the process prematurely so that no signatures can be provided.
No. Swisscom does not have access to the documents. The customer may download a copy up to 30 days after the signature has been added. After that, we delete the file permanently.
The documents are temporarily stored in encrypted form at MS Azure Switzerland (data storage in Switzerland) for 30 days and are available for download during this time. Thereafter, the documents are permanently deleted.
The channel for data transmission between the systems or to the client is always encrypted using SSL. For the transfer into or out of the data storage, the data is therefore encrypted twice; the data itself is encrypted for storage and the transmission channel is encrypted.
Only the contracting parties. The documents are stored in encrypted form for the signing process and are automatically and permanently deleted after 30 days.
Release of the electronic signature is protected with a personal PIN code or with biometrics (via FaceID or TouchID). A signature can only be released with this second factor.
Swisscom Sign is fully FADP and GDPR compliant.
When the document is signed, a hash value of the document is also signed. This hash value is a checksum that can be calculated from the document. When checking the signature, this checksum is recalculated and compared with the signed one. If the document has been changed in the meantime, these checksums no longer match and the user would be informed accordingly that the document's content has changed.
On the federal government website below, you can upload a document and check, free of charge, whether the qualified electronic signature is valid. To do this, visit this site: https://www.validator.admin.ch(opens in new tab)
A scanned signature does not meet the requirements for a qualified electronic signature. So, if you sign a sheet of paper, scan it and use it digitally, it is not legally equivalent to your handwritten signature. This is because it can easily be forged or reproduced.
