Radio-frequency identification (RFID) technology allows for fast and accurate data acquisition of objects without touch. However, existing methods for identifying missing tags do not address the issue of missing unknown tags. Therefore, we propose a priority-based strategy to improve the identification process.
Radio-frequency identification (RFID) technology by transmitting radio waves to the target area and attaching to the object battery-free RFID tags. It can accomplish the fast, timely, and accurate acquisition of the relevant data of the object without touching the identified object. In practical applications, there may be problems where products that have not been warehoused are missing, which we call a missing unknown tag problem. The existing missing tag identification methods are not well suited to the scene, and the missing tag identification method containing unknown tags only takes into account the problem of known tags and unknown tags appearing in the same area and cannot solve the problem of these missing unknown tags. Therefore, we propose a priority-based strategy for missing unknown tag identification (PMUTI), which improves the identification process by means of the priority strategy. The method of sequential marking for unknown tags that have been missing is convenient for warehouse managers to make quick judgments and processing. The experimental results show that the PMUTI outperforms existing methods.
