摘要： Systems (100) and methods (400) for Radio Frequency Identification (“RFID”) security tags. The methods comprise: concurrently reading the RFID security tags and locator tags to obtain unique identifiers thereof and Received Signal Strength Indicator (“RSSI”) measurements therefore, where the RFID security tags are respectively coupled to inventory items located within a facility and the locator tags are placed at locations within the facility so as to respectively define a plurality of Zones Of Interest (“ZOIs”) in which inventory items may reside; and determining which ZOI of the plurality of ZOIs each said RFID security tag resides within based at least on the RSSI measurements, a number of times each locator tag was read, read times specifying when the locator tags were read, differences in read times for the locator tags, and known locations of the locator tags.

摘要翻译： 用于射频识别（“RFID”）安全标签的系统（100）和方法（400）。 这些方法包括：同时读取RFID安全标签和定位标签以获得唯一的标识符和接收信号强度指示器（“RSSI”）测量，其中RFID安全标签分别耦合到位于设施内的库存物品，并且定位器标签 被放置在设施内的位置，以便分别定义多个可以存在库存物品的兴趣区域（“ZOI”）; 以及至少基于RSSI测量确定每个所述RFID安全标签所驻留的多个ZOI的ZOI，读取每个定位标签的次数，指定何时读取定位器标签的读取时间，读取时间的差异 定位器标签和定位器标签的已知位置。
