Signing a loan application through a bank application, an electronic request to change an insurance company, an invoice delivered via e-mail. Digital documents and electronic communication are commonplace in various industries today. How is it that many things that in the past required personal contact can now be handled remotely? And are digital signing and electronic communication safe at all?
We consider the terms “improved electronic signature” and “advanced electronic signature” interchangeable and refer to the same thing, namely an advanced electronic signature that meets the requirements set forth in the European regulation eIDAS (Regulation No. 910/2014).
Simple, advanced and qualified electronic signatures differ mainly in the legal certainty they offer. The higher the level of legal certainty, the more suitable a particular level of electronic signature is for securing transactions of higher value. Of course, there is also a difference in the process of verifying the identity of a person or entity when issuing a certificate for a given signature.
