Abstract: The invention relates to an assembly (6) of a plurality of identical insertion bodies (1), wherein each insertion body (1) has an RFID tag (2) as an electronic or electromechanical transmitter and/or receiver device. The insertion bodies (1) are connected to one another, one next to the other or one behind the other by means of one or more connecting elements (28), wherein the connecting elements (28) are designed to be torn off (4) mechanically by an external force effect (F) on a single insertion body (1). In this way, the connecting elements (28) can form, when combined as a type of magazine (6), a linear arrangement for a pneumatic or electrical nail gun device or bolt gun device (20) as an insertion device, in order, for example, to be inserted into pallets (25) for the purpose of marking them.

Abstract: In a method and an apparatus for preventing concealed, unauthorized wireless data access, a communication and identification element (1) which belongs to a transaction or identification system and wirelessly interchanges data has an electrical or mechanical interruption element (2) which prevents the wireless data connection (4) and is permanently in the interrupted position. The sensor elements (7) integrated in the communication and identification element can convert the acting force into an electrical, capacitive, resistive, inductive or piezoelectric signal, with the result that the interruption of the wireless data connection is cancelled during the time of the action of force.
