A recently granted patent (Publication Number: US11995498B1) outlines a method for electronic devices connected to RFID readers to identify specific items from a group of items within the RFID reader's range. The method involves receiving digital identifiers from RFID tags associated with the items, determining item relevancy based on metrics like proximity or movement relative to the RFID reader, displaying item data on the device's screen ordered by relevancy, receiving feedback on the displayed data, and updating item relevancy accordingly. The patent also includes provisions for determining relevancy based on factors like signal strength, item movement towards the reader, and user feedback, ensuring efficient item identification.

Furthermore, the patent details methods for sending digital identifiers to a network, receiving item data from the network, and incorporating authentication information associated with the electronic device. By leveraging metrics such as proximity and movement, the method enhances the accuracy of item identification, providing users with relevant item data displayed in order of relevancy. The authentication process considers various factors like item location, time of data reception, device type, and user identity, ensuring secure and authorized access to item data. Overall, the patented method offers a comprehensive approach to item identification using RFID technology, optimizing the user experience and operational efficiency in various applications.
