Top Use Cases

Cooperation between Swisscom Sign and PrivaSphere enables lawyers to transmit documents to Swiss authorities digitally in a legally compliant manner. Swisscom Sign supplies the qualified electronic signature (QES) required for the legal recognition of the documents, while PrivaSphere, an approved delivery platform, guarantees the secure transmission in accordance with the Ordinance on Electronic Service in Civil and Criminal Proceedings and Debt Enforcement and Bankruptcy Procedures (VeÜ-ZSSV). Lawyers can download a digital receipt that serves as legally valid proof. This solution replaces the registered letter and provides an efficient, secure and legally protected digital workflow for legal communications. 

A new client instructs a lawyer to represent them in court in a complex legal dispute. In order to act on behalf of the client, the lawyer requires a legally binding delegation of authority from the client. This is issued digitally and submitted to the client for signature. Using Swisscom Sign, the lawyer can subsequently sign the document with a qualified electronic signature (QES) to guarantee its authenticity and legal integrity. The digitally signed document is then sent to the competent court, where it is recognised as legally valid. The entire process is efficient and paperless, without the need for physical signatures or the postal service.

Swisscom Sign’s account opening process enables end-to-end digitalisation, independent of time or location. This completely eliminates the inconvenience of going to the bank, which is tied to opening hours. Thanks to the secure signature processes and fast turnaround, you save time and create a positive customer experience that fulfils modern requirements.

A bank issues a credit agreement for a business customer and wants this to be signed digitally in a legally binding manner. Swisscom Sign enables the bank to provide the agreement with a qualified electronic signature (QES), ensuring the authenticity and integrity of the document. The digitally signed agreement is made available to the customer via their own banking system, making the entire process efficient and paperless. The use of QES ensures that the agreement fulfils the legal requirements and is legally binding.

A fiduciary provides services to clients who want to submit their tax returns digitally. In some cases, such as with company tax returns or legally sensitive documents, the cantonal tax authorities require a qualified electronic signature (QES) to make the submission legally binding. Swisscom Sign allows the fiduciary to sign these documents digitally, ensuring that the submission fulfils the legal requirements. This saves time, increases efficiency and guarantees that the transaction is legally valid.

A fiduciary issues the annual financial statement and the associated auditing report for a client. These documents require a legally binding signature to ensure their validity. Using Swisscom Sign, the fiduciary can add a qualified electronic signature to the statement and the report. The QES guarantees the legal recognition of the documents and enables them to be quickly and efficiently forwarded to clients, banks or other relevant parties without the need for physical documents.

With Swisscom Sign, it is easy to sign rental agreements digitally, independent of location. Registering for Swisscom Sign through the app is quick and simple. Tenants and landlords can then sign the agreements remotely, with no need to meet in person or send documents by post. This significantly reduces the time to market and ensures a fast turnaround, which is appreciated by agents and customers alike.

A buyer and a vendor agree the sale of a property but want to conclude a legally binding preliminary contract before public notarisation at the notary’s office. With Swisscom Sign, both parties can sign the preliminary agreement digitally with a qualified electronic signature (QES). This guarantees that the agreement is legally valid and secure without the need for the parties to be physically present. The preliminary agreement can be subsequently sent to the notary in preparation for the notarisation, making the entire process more efficient.

A local council receives an application for a commercial licence from a company. After checking the documentation, the council issues the licence digitally. With Swisscom Sign, the licence has a qualified electronic signature (QES), which guarantees its authenticity and legal validity. The applicant can use the digitally signed document immediately, for example to register with other authorities, while the digital process saves the council time and money.

A building control authority issues a notice authorising a building project, which is legally binding for the developer. In order to send the notice in a legally valid, digital manner, a qualified electronic signature is added to the document using Swisscom Sign. The QES guarantees the document’s authenticity and integrity, meaning it is legally equivalent to a version with a handwritten signature. The developer can receive the notice securely and digitally and then use it for subsequent steps in the process without the need for it to be sent by post.

FAQs

Swisscom Sign is more than a digital signature: the qualified electronic signature (QES) is equivalent to a handwritten signature under Swiss law and is valid within the entire jurisdiction of Switzerland. With a QES, you can electronically sign, with legal effect, all documents that would previously have been signed by hand (simple written form).

If you need to sign a document that falls under European jurisdiction, please choose our eIDAS-compliant QES.

To be able to electronically sign your documents with Swisscom Sign, you will need:

  • A smartphone
  • My Swisscom app (for Switzerland) 
  • Swisscom Sign app (for countries outside Switzerland) 
  • Successful identity check with a valid ID document

Your signed documents will be automatically deleted after the signature process is completed (30 days). You should therefore download your documents and save them to your device or the cloud before this.

If you have been invited to sign a document, you can download the signed document again within 30 days. To do this, click on the link you received by e-mail.

With the Swisscom Sign Cockpit, you can see all your signature processes from the past 30 days in the cockpit.

On this Swiss Confederation web page, you can upload a document and perform a free check of whether the qualified electronic signature is valid.

A scanned signature does not meet the requirements for a qualified electronic signature. As such, if you sign on a piece of paper, scan it and use it digitally, it is not legally equivalent to your handwritten signature. This is because it is easy to fake or reproduce.
