Today, despite the rise of electronic document or e-document, paper document remains the support of reference whenever one has to materialize a transaction. Culturally, we need to have concrete elements to materialize a right or an operation. As for the cultural supports, one can estimate life expectancy of books and magazines to some decades.

Paper document is a necessary pain. If today many more or less secured systems for electronic documents management exist, nothing like it existed or nearly exists for paper documents. Once the document is produced, nothing could assure that this one will be used in the conditions foreseen by its creator. He could not prevent an undesirable diffusion, nor avoid a falsification or a misappropriate use of the document.

To make paper document a secured and reliable media, we suggest to you a solution using new technologies concerning documents. This solution is concretized by an international patent (USA, Europe and Japan patent based on a initial apply in France). In this bulletin we display a preview of the offered solution as well as significant examples of its applications.
