‍Whatdoes a digital signature have to comply with?

A digital signature is the electronic counterpart of a handwritten signature. But not all digital signatures are the same. To be considered valid and reliable, a digital signature must meet specific criteria:

1. Authenticity: The signature must verify the identity of the signer.
2. Integrity: The signature must guarantee that the document has not been altered since it was signed.
3. Irrefutability: The signer should not be able to later deny the signature.

‍

‍Whyare QES signatures so special?

Qualified electronic signatures (QES) represent the highest standard in digital signatures. In addition to being legally valid, they are considered equivalent to handwritten signatures for documents with significant legal effect, such as notarized deeds, mortgage deeds, insurance policies and certain employment contracts.

How can I set up a digital signature?

To set up or request a digital signature (QES), you need a qualified "signature creation tool". An accredited certification body, such as Banqup Sign in Billtobox, can help you with this. Billtobox is part of Unifiedpost and they are recognized as a trusted eIDAS service partner.

The importance of identity verification

A critical element in QES signatures is the verification of the signer's identity. This is usually done in a face-to-face meeting or through equivalent processes, such as a video call. Only after the identity has been thoroughly verified can an individual obtain his or her first QES. In addition, multiple authentication is always required. For example, the signer must enter a PIN to verify validity.

When do you need a QES?

QES signatures are especially relevant in situations with major legal implications, such as:

• Large commercial agreements
• Major sales contracts
• Mortgage documents

‍

In these cases, a QES provides not only legal security but also peace of mind in a world where digital transactions are becoming more commonplace. It is the ultimate assurance of the integrity and authenticity of your electronic documents.
