A RFID system applying to a three-dimensional jigsaw is provided. A first transfer apparatus includes a pusher plate which moves groups of wrapped bakery products onto the vacuum turntable and which retracts to facilitate the formation of a subsequent group of wrapped bakery products as a previous group is being transferred to the vacuum turntable. A live movie of a speaker together with the speaker’s flipping still images or slide show can be viewed interactively within the same video display screen. The two electromagnetic valves are controlled to operate by a remote controller and actuate the deadbolt to move to a limited position. By forming an etching hole at each corner of the protrusion and eliminating the residues using the etching hole, the short-circuit between the storage capacitor and the data line is obviated. A positive pressure can be maintained within the pipes during applications.
