We want to deliver customer value through innovation. It was therefore clear to us that we wanted to use our own verified identities for the electronic signature process. It was crucial for us that the solution did not require any additional effort from our customers due to a need for extra identification. The signature solution from SwissSign effortlessly facilitated this, enabling us to offer our customers a faster and more convenient process.
