1. A method of exchanging digital data between a plurality of users, each of the users being provided with a portable device (10) for sending and receiving digital data, the method being characterized in that it comprises the following steps:
- inputting said digital data for exchanging between users into a first computer installation (12);
allocating at least one determined identity code to each input item of digital data;
transferring each of the determined identity codes as allocated in this way to the portable device of the user whose digital data associated with said determined identity codes has previously been input into said first computer installation;
establishing connections between the portable devices of different users, over which the devices transmit between each other their at least one determined identity codes;
transferring the determined identity codes received in this way from each of the portable devices to said first computer installation; and
making available to each user of said portable devices the digital data associated with said determined identity codes as transferred in this way.

12. A method of exchanging digital data between a plurality of users, each of the users being provided with a portable device (10) for sending and receiving digital data, said device having a unique identity number, the method being characterized in that it comprises the following steps:
- inputting said digital data that is to be exchanged between users into a first computer installation (12);
allocating said unique identity numbers to said input items of digital data;
establishing connections between the portable devices of different users whereby the devices transmit to each other their unique identity numbers;
transferring from each of said portable devices to said first computer installation the determined identity numbers that been received in this way; and
making available to each user of said portable devices the digital data associated with the unique identity numbers as transferred in this way.
