Industry challenges
Why Swiss financial institutions must adopt digital signatures
The financial industry faces complex challenges.
Regulatory requirements are becoming stricter, customers expect seamless digital experiences, and competitive pressure is increasing. At the same time, outdated processes with manual signatures slow efficiency and increase costs.
Digital signatures under ZertES and eIDAS provide the solution here – yet many institutions still hesitate. The following challenges show why switching to qualified electronic signatures is necessary.
Inefficient processes
Long processing times with physical signatures delay processes and postal delivery times.
- Switching between paper and digital leads to errors, duplicate work, and process inefficiencies.
Customer expectations
Customers abandon processes when they have to appear in person for signatures. Digital signatures increase the conversion rate.
Banks with QES solutions (qualified electronic signatures) set the benchmark – without digital signatures, you risk losing customers to competitors.
Compliance & legal risks
Manual signatures do not meet the requirements for qualified electronic signatures (ZertES) in legally critical processes. They are neither audit-proof nor scalable.
Physical archiving is expensive and risky. Digital signatures, on the other hand, ensure long-term, audit-proof validation.
