    • The invention relates to a detection label provided with a passive resonant circuit which is configured to emit an identification code when the passive resonant circuit is introduced into a first electromagnetic interrogation field, wherein the label is further provided with a memory and an active circuit comprising a transmitter and a receiver, wherein the active circuit is configured to emit information which is stored in the memory with the transmitter when the active circuit is introduced into a second electromagnetic interrogation field comprising a first predetermined code, which second electromagnetic interrogation field is received with the receiver, characterized in that the label is configured, in response to the receiving of the second interrogation field, when the second interrogation field comprises a second predetermined code, to adjust a status of the label such that the passive resonant circuit does not emit the identification code when the passive resonant circuit is introduced into the first electromagnetic interrogation field.
