Abstract: An electronic label (1) is used to mark a container (2, 6). The label includes a radio identification element (RFID, Radio Frequency Identification Device) (10, 11) and which is intended to be placed inside the container (2, 6). The electronic label (1) is specifically adapted to the position thereof inside the container (2, 6). Using the present arrangement, the electronic label (1) is inaccessible and, thus, difficult to destroy or change. In this way, the container (2, 6) is marked in a reliable, even permanent, manner, thereby enabling the information contained on the label (1) to be used effectively to combat theft, forgery or counterfeiting and to manage a deposit system.
