摘要:
The invention relates to closable containers and a method for retrieving a shut state and/or a location of a closable container, wherein the container has at least one RFID chip having a connected near field antenna and a far field antenna. The RFID chip is arranged at the first or at the second container part and the far field antenna is arranged at the other one of the first and second container part, respectively. In the closed position of the container, a noncontact electromagnetic coupling takes place between the near field antenna and the far field antenna. Due to the interaction of a sending unit and a receiving unit, a response signal can by generated by RFID chip and transmitted. The range of said response signal depending on the shut position of the container.
