What is a digital stamp?

The company stamp is a print containing all the information identifying a company. Including: company name, company address, company contact information, RCS number...

The company stamp is used to authenticate all administrative documents.

This stamp may be affixed to all official company documents. For example, they may be quotes, invoices or other professional document on which the company must be identified.

With KEYMO, the traditional corporate stamp has evolved into a digitalized version.

In addition to the features offered by the stamp, the digital stamp allows you to :
 To secure company documents,
 To save time in the administrative procedures,
 To reduce the costs associated with stamping (ink, stamp…)
 To increase productivity
 To sign documents electronically,
 Ability to access all company documents quickly (online documents)
 To adapt to new technologies
 To modify the company information directly online

Why use a digital stamp?

Affixing an electronic seal does not imply any commitment on the part of the company with respect to the sealed document but ensures the integrity and authenticity of the document.

The denomination 'electronic seal' requires by default to meet the criteria "advanced or advanced with qualified certificate" with the same principles as for the electronic signature.

The use of an electronic seal (advanced, qualified certificate) rather than an electronic stamp (simple) depends on the value that one wishes to give to the sealed document. Documents deemed sensitive or of high value may be specifically subject to an advanced seal with or without a qualified certificate.
