Abstract
A method for enhancing the accuracy a Radio Frequency IDentification (RFID) system which may exhibit inconsistent RFID tag reporting behavior. The method includes the steps of (i) establishing a timeout setting indicative of the time that each interrogating antenna transmits RF energy within a respective read field, (ii) evaluating/comparing reporting results over multiple interrogation cycles to determine when an RFID tag exhibits inconsistent reporting behavior within the read field and (iii) increasing the timeout setting of the respective interrogating antenna to enhance the energy harvested by an RFID tag/device during each interrogation cycle. In lieu of, or in addition to, increasing the timeout setting, the method evaluates the responses received over multiple cycles and accepts such responses as being valid only when the same response is obtain over consecutive/sequential interrogation cycles. That is, the system evaluates the results of several cycles before accepting the validity or veracity of the response.
