1. A method for enhancing the accuracy a Radio Frequency IDentification (RFID) system exhibiting a propensity for inconsistent RFID tag reporting, the RFID system having at least one interrogating antenna for transmitting RF energy within a read field during an interrogation cycle, and an RFID tag within the read field communicating with the antenna;

  • the method comprising the steps of;

    establishing a timeout setting indicative of the time that each interrogating antenna transmits RF energy within a respective read field;

    determining when an RFID tag exhibits inconsistent reporting behavior within a read field; and

    increasing the timeout setting of the respective interrogating antenna when the inconsistent reporting behavior is exhibited.
