Abstract: An object tracking and locating device includes two or more identical units each having a receiving/transmitting module coupled to an antenna member for receiving and transmitting signals, a ZigBee wireless transmission module coupled to the receiving/transmitting module for processing the signals, and an alarm device coupled to the ZigBee wireless transmission module for generating a signal to indicate the spacing distance and the direction between the units, and the two or more identical units may be easily and quickly manufactured with a simplified manufacturing procedure and a reduced or decreased manufacturing cost.

Abstract: An IC card includes an opening formed in a bottom portion of a casing, a circuit board engaged into the casing, one or more batteries attached to the circuit board and received in the opening of the casing for reducing the thickness of the IC card, a processor and an antenna member are attached to the circuit board and electrically coupled together, and a cover member is attached to the casing and engaged onto the circuit board for shielding the circuit board and for retaining the circuit board in the casing, and the cover member includes a lid aligned with the batteries and openable to expose the batteries and to allow the batteries to be changed with a new one when the batteries have been consumed.
