On October 10, 2008, at a single stamp belonging to the sheet of 50, an unusual appendix with barcode appears. Primary objectives of Poste Italiane are to speed up and be able to monitor transfers and deposits of philatelic material from branches to peripheral offices (and vice versa) through the aid of a handy optical reader of barcodes, already distributed in all post offices of the territory.

The match Francobollo-Appndice soon first intrigued and then literally excited the philisti of the Italian area to such a extent that in just a few months from the first issue all the major magazines and web portals of the sector began to address the topic.

This success is mainly due to some fundamental aspects. First of all, the circulation: if the availability of a single issue, for example of the stamp "Giornata della Filatelia" of 10/10/2008, is of three million and five hundred thousand pieces, the single stamp with barcode ( commonly called "the Barre"), finding one appendix per sheet of 50, is available in only seventy thousand copies.

In addition, it was precisely the value of this circulation (70.000 Barre) that made people talk a lot about themselves.
