Electronic signatures: simple, efficient and legally valid

How does Sign work?

Sign replaces the traditional process of document printing, signing, scanning or sending by post with a fast, simple and legally valid digital signature.

In 4 simple steps

You submit your document and contact information to our platform, with a request to sign the document. An invitation will be sent to the addressee by email or SMS to sign the document. The recipient signs the document via Sign, and you both receive a confirmation of signing and the signed document.

3 levels of signature

To sign a document digitally, you need to make a distinction between 3 levels of signature, as defined by the eIDAS Regulation. Sign offers all 3 levels. It’s up to the sender to determine what level of signature is needed.

Let’s look at all 3 levels.

Unifiedpost Sign

Level 1: Standard Electronic Signature (SES)

This is the most basic form: a scanned image of a handwritten signature placed in the document, or one ‘scribbled’ using the mouse or tablet pen. Standard digital signatures can have legal consequences, but this depends on national legislation. Sign offers signing via scribble.

“Digital signing is the future and for us it is a way to optimize our services.”


Level 2: Advanced Electronic Signature (AES)

An advanced electronic signature uses mathematical techniques to associate the message with a unique code, which is derived from the message itself and the identity of the sender. These signatures are seen as more reliable, but its validity can be contradicted in court.

Sign offers the following options at this level:

  • SMS: a SMS is sent to the mobile phone of the addressee with a code that he/she has to enter on the signing page to get the document signed.
  • itsme confirm: you can sign a document with an ‘Advanced’ sign level.

Level 3: Qualified Electronic Signature (QES)

A qualified electronic signature works in the same way as an AES, with 1 big difference: it uses a certificate issued by a Trusted Third Party. The signature is generated by trusted devices: governments issuing qualified certificates as a national digital identity, or via commercial organisations. Following the eIDAS amendment, a QES has the same legal validity as a handwritten signature.

Sign offers the following methods:

  • eID: you can sign the document using the eID card with certificate and pin.
  • itsme Sign: the document is signed at a ‘Qualified’ level.

“Making mistakes is a thing of the past since the introduction of digital signing.
The signature is always in the right place and counts for the entire document.
No more signing on every page.”

‘Digital Authentication?’

Because electronic signatures have the same legal status as handwritten signatures, a digitally signed document has the same status as one signed by hand. However, the electronic signature must still comply with the requirements that are set by law.
