The present invention relates to a tag system for loss prevention using a smart phone, which comprises: a position transmission tag which is provided to include short-range wireless communication standard, transmit position information, or receive a call signal to output a vibration, an LED lighting or a voice signal; a portable cradle which is provided to hold the plurality of position transmission tags in numbers to charge them, and transmit and receive position information by the position transmission tag and the short-range wireless communication standard; a smart phone including a position information application to transmit and receive the position information or a call signal by the position transmission tag or the portable cradle and the short-range wireless communication standard, and project the transmitted position information on the map. According to the tag system for loss prevention of the present invention, the portable cradle which can accommodate the plurality of position transmission tags and can carry on and charge of the position transmission tags, thereby storing and managing of the position transmission tags can be easily. Since the positions of an article or a person with the attached position transmission tags can be identified via a smart phone, by triangulation using the smart phone, the position transmission tag, and the portable cradle, it may be useful in underground or indoors where GPS signals do not reach, and the position transmission tag can be miniaturized and battery lifespan can be increased to improve the reliability of the device by not using the GPS. |
