Abstract

A dispenser configured to discern a specific source of material from a plurality of other sources of material, wherein the specific source of material and the plurality of other sources of material all comprise at least substantially similarly shaped bodies and spray heads, wherein the specific source of material comprises an identifier associated therewith, the identifier not being associated with the plurality of other sources of material. In a preferred embodiment, the dispenser comprises an interrogator, operationally coupled to the controller, for interrogating the identifier to determine whether the source of material is a specific source of material. An actuation mechanism is inhibited from causing the dispensing of the material if the interrogator does not detect the specific source of material. In preferred embodiments, the interrogator may be a sensor or a reader, and the identifier may be a magnet, a barcode, or an RFID transponder that is compatible with the specific interrogator chosen.
