ROI Calculation Logic

This chipless tag technology, which forms transmission lines on a dielectric substrate, could reduce manufacturing costs by approximately 2/3 compared to conventional IC chip-based RFID tags (unit cost ~$0.07/tag (AI est.)). For an adopting company using 10 million tags annually, this translates to a material cost reduction of ~$0.05 per tag (AI est.), totaling ~$500K/year (AI est.). When combined with reduced misreading/rework costs from improved accuracy and optimized inventory management, the total economic impact could exceed ~$650K/year (AI est.).
