A method is provided including: sensing that a reader is located within a preset distance from an electronic device; determining a Service Identification Module from a plurality of SIMS that are available in the electronic device; and communicating with the reader using information stored in the SIM. The results of a viewer completed demographic survey are used to generate a database known as a bit mask that is made up of the viewer’s demographic data. Practical implementations of sensing load parameters are included. A spot shape of the light emitting diode and a spot shape of the photodiode are both formed in a square shape. A confectionery product containing oils of the invention is also described.
