This system provides a beverage dispenser coding device which is able to encode a large number of different unique objects. For this the device comprises a primary inductance coil (46) provided on an activator coil unit for use in opening the stopper valve, a secondary inductance coil (44) provided on the stopper valve, rectifier connected to the secondary coil for rectifying and regulating current generated in the secondary coil, serial identifier circuit (40) means connected to the rectifier means for making a pattern of impedance changes in the secondary coil, the pattern being a serial bit pattern representing an identification number, an oscillator (48) connected to the primary coil, and demodulator and decoder means (50) connected to the primary coil for detecting and decoding the pattern to obtain the identification number. <IMAGE> |
