The eIDAS-compliant qualified and advanced electronic seals from Swisscom Trust Services enable efficient digital document processes. They help save paper, printing, analog office seals, and postage costs while speeding up document processing and saving time on administrative tasks.

Our electronic seals offer more than a digital alternative to traditional official seals. They revolutionize how you handle large quantities of documents such as mailings, invoices, general terms and conditions, certificates, or official certificates typically issued by companies or authorities. Our solution allows you to streamline your processes, increase efficiency, and focus on more strategic tasks.

Furthermore, electronic seals enhance security by using advanced encryption technologies that guarantee the integrity of the documents and ensure their traceability.

Also, at the software partner's request, each electronic seal can be combined with a qualified timestamp, providing additional assurance of integrity and authenticity regarding the time of sealing the document.
