Method for Managing a Mode of Operation of a Contactless Tag and Corresponding Tag

A method is provided for managing the operating mode of an electronic tag, including at least one communication module for communicating with at least one control device and a memory for storing at least one tag identifier specific to the tag and transmittable by the tag to the at least one control device. The method includes, following reception of a deactivation instruction upon which the tag goes from an activated state to a deactivated state, a deactivation step, in which the transmission, to the control device, of the tag identifier is inhibited and in which the tag responds to a reactivation instruction by re-enabling the transmission of the tag identifier to the control device.
