<p>The support (1) has switches (S1, S2) of an integrated circuit (3) opened in openings of packaging units (V1, V2), respectively, where the switches are connected in parallel. The circuit is arranged to cooperate with an electronic unit (6) e.g. radio frequency identification (RFID)- microchip, to determine a value correlated to a filling degree of the support based on the number of closed and/or opened switches. An antenna (7) e.g. slot antenna, working with the electronic unit transmits the value, where the electric power for the electronic unit is introduced in a contactless manner. An independent claim is also included for a system comprising a goods support and a receiver device.</p> |
