ABSTRACT:
A non-contact coding device working in a magnetic field, for use with a liquor bottle stopper and electromagnetic valve system. The stopper can be provided with a secondary coil and a diode bridge/rectifier circuit for powering a serial number identifier chip, which serially varies the impedance of the secondary coil. A primary coil on activator unit is coupled with the secondary coil to provide power and read the serial number. The activator unit can also be provided with a number of Hall effect transducers, and the stopper a number of metal peg holes, such that when the transducers are aligned on top of the holes, the presence/absence of metal pegs can be read to reproduce the serial number.
