Abstract
The currency note (10) is provided with a first and a second integrated circuit (1,3), that each have an antenna (2,4). The antennas (2,4) preferably operate at different frequencies. Each of the integrated circuits (2,4) comprises a memory in which a chip code and a combination code are stored. The combination code has been programmed only after integration of the integrated circuits (2,4) into the currency note (10), and allows the recognition that the first integrated circuit (1) is part of the same currency note (10) as the second integrated circuit (3), when a plurality of currency notes (10) is read out at once, wirelessly.
