Abstract: Authentication method that provides: to make an authentication device, randomly attaching a plurality of reflecting particles, such as glitter, on a support; a first step of acquiring, with an optical acquisition device, at least two first images of the authentication device, the two first images each being acquired according to different lighting conditions; a first step of encoding each of the two first images in order to determine at least a first identifying indicator to be attributed to the authentication device.

Abstract: Apparatus to make business cards comprising a supply operating unit to supply a plurality of pairs of sheets and a printing unit configured to print distinctive signs on at least one printable surface of the sheets. The apparatus comprises a coupling unit configured to reciprocally couple, with their coupling surfaces opposite the printable surfaces, the sheets of the pair, an electronic device conformed as a sheet being associated to one of the coupling surfaces; and an electronic writing unit configured to introduce encoded information readable by a reader into the electronic device.

Abstract: Network communication architecture comprising portable electronic telecommunication devices (12) provided with a processor and able to access pre-recorded sounds and/or images and to reproduce them. The access to the pre-recorded sounds and/or images can be activated by means of an enabling support (13), outside the portable electronic telecommunication devices (12) and provided with an enabling support element (15).
