Smart Registration

legally compliant identification and registration for electronic signature

The electronic signature requires a unique identification of the user. Our Smart Registration Service (SRS) enables the coupling of identification with an authentication method for electronic signing without re-identification for each signature. This includes a bundle of various identification methods, e.g. SRS Video, SRS Bank, SRS Direct or SRS eID. The SRS offers a standardised interface that you can flexibly integrate into your workflow to enable your end customers to use electronic signatures. You can find an example of such an integration on our identification page.


With a one-time registration and identification by SRS, your customers can sign multiple times and use the Signing Service. Depending on the identification method, signing can take place over a certain period of time, e.g. 5 years with a video identification. In the signature process, you only use authentication method to express the declaration of intent for the signature.


You choose the most suitable identification methods for your process and offer this to your end customers based on their requirements, matching:

  • the legal area EU or Switzerland in which the signature should take place,
  • the legal weight of the signature: qualified or advanced
  • the technical possibilities that your end customer has.

  2. The service provider selects the appropriate identification methods for its customer portal.
  3. Swisscom opens an order with the identification partner and provides a URL for the end customer in the service provider’s customer portal.
  4. The end customer is redirected to the portal of the identification partner and goes through the identification process according to the selected identification method.
  5. The identification partner provides Swisscom with the evidence data of the identification and the registered authentication method.
  6. Swisscom sends an SMS to the end customer via the mobile number specified in the identification process with a request to agree to the terms of use.
  7. The end customer opens the link in the SMS and agrees to the terms of use on the Swisscom portal.
  8. The service provider has the option of using the end customer’s identification data for its own purposes.

Connection of your own identification method

As a service provider, partner of signature application or identity provider, you also have the option of connecting your own identification method to the Smart Registration Service. The integration requires compliance with the requirements of the legislation and applicable regulations as well as an implementation concept and, if necessary, an audit. We support you in the creation of the implementation concept and the audit process and submit the release for your procedure to the responsible authorities for approval.
