## TL;DR

This paper introduces a new algorithm to improve RFID tag inventory efficiency in cabinets with densely stacked tags.

## Contribution

A novel algorithm that prevents repeated inventory of tags by different antennas in RFID cabinets.

## Key findings

- The algorithm achieves 100% inventory accuracy for 560 stacked tags.
- Inventory time is reduced by 40%, significantly improving efficiency.

## Abstract

This paper explicitly proposes a novel algorithm to enhance the inventory efficiency of densely stacked tags in a radio frequency identification (RFID) cabinet. By flexibly setting the inventoried flags, tags are not repeatedly inventoried by different interrogator antennas in the RFID cabinet. Comprehensive experiments are conducted to validate the proposed algorithm’s feasibility. The experimental results show that for 560 stacked tags, the proposed algorithm achieves 100% inventory accuracy while reducing inventory time by 40%, thereby significantly enhancing the efficiency of tag inventory management.
