Abstract
A radio frequency identification (RFID) dispenser that includes low cost electronic components that can read and write to the tag of a refill cartridge. In one embodiment, the reader utilizes a multi band pass filter to convert the radio frequency identification into a digital signal that is processed by a controller to perform a dispensing function representative to the code of the tag. In another embodiment, the controller utilizes an internal comparator to convert the radio frequency identification into a digital signal that is processed by a controller to perform a dispensing function representative to the code of the tag. The dispenser in both embodiments also includes a pair of transistors that write to the RFID tag of the refill cartridge. A dispenser according to the invention also includes the capability to read and/or write to tags upon cartridges employed by the dispenser, and augmenting the operation of the dispenser as a function thereof. Additionally, a dispenser of variable size is presented that is adaptable, through adjustable partitions or a telescoping cup, to receive and maintain cartridges of various sizes.
