<p>The currency note (10) is provided with a first and a second integrated circuit (1,3), that each have,: in antenna (2,4). The antennas (2,4) preferably operate at different frequencies. Each of he 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 into grated circuits (2,4) with the currency note (10), and allows the recognition of the fir<sup</p> |
