Abstract
Materials and construction for a tamper indicating radio frequency identification (RFID) label are provided to permit the destruction of the label or its properties in the event of attempts to remove the label from a surface to which it has been applied. An adhesion modifying coating is applied to a label surface or portions thereof to affect the relative adhesion strengths between different layers or areas of the label. The adhesion modifying coating can be applied in selected patterns to achieve differential adhesion strengths and resulting differential separation of the label from a surface on which it has been applied.
