A seat assembly includes a seat bottom with a deformable seat shell. The method receives and stores identification information transmitted by the radio frequency device, retrieves the identification information from the first mobile communication device, and inserts the identification information into the communication. A row of UV-LED assemblies which emit light in the visible spectrum can be included so a user can visually see if the apparatus is working. Suitable multiplexing schemes include time division multiplexing, wavelength division multiplexing, code division multiple access multiplexing, as well as various combinations of suitable multiplexing methods.
