Abstract: A portable object includes an antenna and a processor coupled to the antenna. The processor is configured to communicate with an item of equipment according to a contactless communication protocol that contains an anticollision procedure. The processor is also configured to execute a plurality of software modules. The software modules include application modules and a triggering module, which is configured to cause a triggering of the anticollision procedure between the single portable object and the item of equipment. The processor is configured to cause a signal, which is generated by executing the triggering module, to be transmitted from the antenna to the time of equipment.

Abstract: The subject comprises processing means configured for communicating with an item of equipment according to a contactless communication protocol containing an anticollision procedure; the processing means (MT) comprise several application modules (MA1, . . . MAj) respectively associated with several different identifiers (ID1, . . . IDj), and triggering means (MDCL) configured for causing a triggering of the said anticollision procedure between the said object and the said item of equipment.
