Abstract

Dispensing systems are disclosed which utilize electronically powered key devices and/or identification codes associated with a refill container to preclude the need for mechanical keys. A first embodiment of the device utilizes a matching code stored in a radio frequency identification tag or bar code associated with a fluid refill container and an identification code associated with the dispenser housing. Matching of the codes by a controller allows for continued use of the dispenser via some type of operational mechanism. Another embodiment employs a key which carries the matching code wherein matching of the codes allows for actuation of a motor actuated pumping device. Yet another embodiment employs a blocking mechanism to prevent use of a dispenser'"'"'s push bar if a key and dispenser housing do not have matching codes. And yet another embodiment requires the use of a key that has a matching code that matches the dispenser'"'"'s identification code in order to permit initial access to the dispenser housing.
