Abstract

The invention relates to a product carrier comprising a first packaging unit wherein when opened a first switch of an integrated circuit of the product carrier is opened and at least one second packaging unit wherein when opened a second switch of the integrated circuit is opened. The circuit is configured and/or arranged to cooperate with electronic means so that a value correlating with the degree of filling of the product carrier can be determined on the basis of the number of closed and/or opened switches. Further, an antenna cooperates with the electronic means to transmit said value, the electric power for the electronic means may be introduced without contact, and the first and the second switch are connected in parallel.
