UHF-RFiD Based Advanced Visitor Management System

Abstract

Visitor management in large organisations, cam- puses and residential complexes is increasingly challenged by scale, security requirements and the need for real-time data. Tra- ditional paper-based or barcode-driven approaches suffer from manual delays, limited read-range and vulnerability to spoofing. This paper presents an Advanced Visitor Management System (AVMS) built on Ultra-High-Frequency Radio-Frequency Identi- fication (UHF-RFiD) technology. The proposed system leverages passive UHF-RFiD tags operating in the 860–960 MHz frequency band to enable contactless, long-range (up to 10 m) identification of visitors at entry and exit points. A centralised web-based dashboard provides real-time occupancy tracking, automated log generation and alert mechanisms for unauthorised access. The system was prototyped and evaluated against key performance metrics including read accuracy, throughput, latency and false- positive rate. Experimental results demonstrate a tag-read ac- curacy exceeding 97%, sub-second authentication latency and significant improvement in administrative overhead compared to legacy systems. The AVMS architecture is scalable, cost-effective and compliant with standard data-privacy requirements, making it suitable for enterprise-grade deployments.
