Method for exchanging numerical data, comprises information assembly which stores numerical data and assigned identification codes also portable user units for exchange of identification codes

摘要

Numerical data with identification codes are stored in a server (12) which is linked either directly or through a communication system (14) to user terminals (16). Persons at a conference have portable equipment (10) similar to a smartcard which enable them to exchange the assigned identification codes and then to access the corresponding numerical data either through the communication system, user terminals or a local accessing equipment (18) An Independent claim is also included for a system and equipment suitable to implement the method
