A method of dispensing product includes determining by a processor if product loaded into a dispenser is authorized for use in the dispenser by identifying a reference indication associated with the product; in response to determination that the product is authorized, dispense a first amount of product; and in response to determination that the sheet product is unauthorized, dispense a second amount of sheet product, wherein the second amount of sheet product is different than the first amount. To determine if the sheet product is authorized, a pigment is excited to emit a light with an intensity signature. A portion of the intensity signature is measured and compared to a desired value. If the portion is substantially equal to the desired value, the sheet product is authenticated.
