The invention relates to an article security label adapted for repeated activation and deactivation using a semiconductor memory element. This label is also deactivatable with the existing deactivator technology. Also, the label can be provided with more than one memory element which can be written and read out again by a read/write device, so that this article security label can fulfil a secondary function as a data carrier.
