Most popular questions
What is a basic signature (SES)?
A basic signature is a one-time SMS or email code used to sign an e-document. It works best when the other party does not have their own e-signature. When sending a document from the CertumSign platform for signing, you can choose how the recipient is authorized – by SMS code or email.
If you choose authorization by SMS code, and the recipient does not have a CertumSign account, they will first receive a code to open the document. This ensures the protection and confidentiality of the document’s content.
Such a signature meets the conditions for maintaining the documentary form. The date and time of signing are confirmed by a qualified time stamp, and the integrity of the document is ensured by a qualified Certum electronic seal. CertumSign sends SMS codes only to European phone numbers.
Who are CertumSign individual plans intended for?
CertumSign individual plans are available to individuals and companies. You can choose between a free account or a paid account with additional features. The account can only be used by one user.
Who are plans for organizations intended for?
