ABSTRACT:
A dispensing device has a photovoltaic vending actuator including a light source coupled to a currency collector, supplying a beam of light at a first wavelength when proper currency is inserted in the currency collector. A light modifying device is positioned to receive the beam of light from the light source and to transmit a beam of light at a second wavelength. A light detector is sensitive to light at the second wavelength and positioned to receive the beam of light from the light modifying device. A circuit is coupled to the light detector for dispensing an item when actuated by the light detector.
