Article in-out tracking system and method based on RFID

Abstract

This invention provides an in/out tracking system and a method based on RFID goods including RFID labels, a reader, a working state control unit, reader antennas and a back end data process unit, in which, the working state control unit is connected with the reader to control the working state of the reader, the RFID label is composed of multiple RFID labels and antennas of which are set in angle solving the problem that labels adhered on metals can't be read and improve the limit of reading angles between antennas of labels and readers. This invention also applies a double verification method to carry out double verification to multiple identity verification cards, and the control unit will convert the system from the standby mode to activation working mode only when the verification is successful. 本发明提供一种基于RFID的物品出入追踪系统和方法，其包括RFID 标签、阅读器、工作状态控制单元、阅读器天线以及后端数据处理单元；工作状态控制单元与阅读器相连，以控制阅读器的工作状态；其中，RFID标签为由多个RFID标签组成，且该多个RFID标签天线相互呈角度设置，解决了附着在金属的物品上的标签无法读取的问题，改善标签和阅读器的天线之间的阅读角度的限制问题；本发明还采用“双重验证”方法，对多个身份验证卡进行双重身份验证，只有当验证成功，工作状态控制单元才能将系统从待机模式转入激活工作模式，该“双重验证”方法必须由交付方和验货方双方当事人同时去激活系统，且能自动记录对于物品的所有权变更。
