Abstract
A beverage dispenser transponder identification system includes a pourer spout for insertion into a bottle containing a beverage, the pourer spout having an electromagnetically actuated stopper valve for dispensing the beverage, the pourer spout having an rf receive/transmit antenna connected to an identification transponder circuit. An actuator is provided by an activator ring for insertion around the pourer spout and has a driver coil for actuating the stopper valve, an rf transmit antenna connected to an oscillator, and an rf receive antenna connected to a decoder. The rf transmit antenna broadcasts an rf signal to the rf receive/transmit antenna which is conducted to the identification transponder circuit which sends an identification signal to the rf receive/transmit antenna which is broadcast to the rf receive antenna and received by the decoder to identify the pourer spout.
