What is a Digital stamp?

Digital stamp is an evolution of the "ink" stamp. It appeared many years ago to allow people to mark, authenticate and certify their official documents.
This imprint affixed by the tool allows in particular to:

 Facilitate document management and processing
 Save time when marking in administrative procedures
 Validate important documents such as paid invoices.

Digital stamp  is the version of the ink stamp adapted to the digital world now essential.
This digital tool allows you to sign documents easily and quickly without having to print, stamp, sign, scan. In addition, this can prevent the maintenance of a printer and the replacement of an ink pad at the slightest change in the information of the company footprint.  

The use of electronic stamp represents a real time saving when stamping your documents.

Why use a Digital stamp?

Today, the use of the company stamp is common in all companies and administrations, even mandatory. 

With the progression of dematerialization, many documents are exchanged electronically and no longer need to be printed. However, the only way to transmit a document is to print it, stamp it and scan it.
To make everyday administrative life easier while maintaining the reassuring and marketing aspect of the ink pad, we created the KEYMO™ digital stamp.
