<p>The invention concerns a method for communicating between a local machine (1) and a back office server (4) using a mobile communication device (2) adapted for communicating with the back office server (4) through a network (3), the local machine (1) being adapted for broadcasting messages over the air, the method comprising the following steps:
- the local machine (1) broadcasts a sonic signal over the air, said sonic signal conveying a local message having a plurality of fields of data;
- the mobile communication device (2) receives the sonic signal through its microphone and demodulates it for extracting the fields of data of the local message;
- the mobile communication device (2) processes at least one field of data for at least obtaining a remote message to be transmitted to the back office server (4) through the network (3) and if necessary detects whether an event has to be triggered on the mobile communication device (2).</p> |
