Object proximity sensor features a portable RFID tag reader

摘要

PURPOSE: A portable RFID tag reader having an object recognition sensor function is provided to activate an RFID tag reader module which an object having an RFID tag contacts. CONSTITUTION: An RFID(Radio Frequency Identification System) tag reception sensitivity measuring unit(120) measures strength of a received RF(Radio Frequency) signal. An object movement sensing unit(130) determines a location of an object having an RFID tag. An RFID tag reader module(150) is activated through a proximity signal of an object sensing unit(140). The RFID tag reader module collects the RFID tag information of the object. A short-distance communication module(170) transfers the collected RFID tag information to a portable terminal(180).
