ABSTRACT:
The invention concerns a method and a system for rapidly establishing a communication, particularly a Bluetooth type communication, between at least one reader and a plurality of communicating objects. Each communicating object and said reader have a communication protocol. Each communicating object has a communication address. The method comprises: the step of defining a unique communication address for all of the communicating objects; the step, for said reader, of determining whether at least one communicating object is present in the environment in which said reader is located, by sending a request to the unique communication address of all the communicating objects; the step, for each communicating object that receives said request, of revealing its presence to said reader by sending a response signal that is time-shifted relative to the response signals sent by the other communicating objects.
