Abstract: The invention provides a closure member (10, 110) for covering and/or closing a container (100, 200), in particular a bottle, the closure member (10, 110) comprising: a shell element (13, 113) comprising an opening (13d, 113d), the shell element (13, 113) being at least partially made of a conductive material, and a transponder (20, 120) comprising an antenna, the antenna being arranged at the opening (13d, 113d).

Abstract: A system is disclosed comprising a near field communication tag that is transformable from a first state to a second state. The system also comprises a server program stored on a non-transitory storage medium that, when executed by a server apparatus, receives a first tag report from a user device in response to the tag being tapped while being in the first state, sends a first response to the user device or to another user device in response to the first tag report being received, receives a second tag report from the user device in response to the tag being tapped while being in the second state, and sends a second response to the user device or to another user device in response to the second tag report being received.
