13.56 MHz RFID Module - From Application to Process Modelling and Effects on Human Health

Abstract

Overview

RFID (Radio Frequency Identification) is a technology widely used in recent years due to its reliability and ease of use. Applications span a broad range of frequencies, but this study focuses specifically on a 13.56 MHz module, typically integrated with Arduino boards.

• Initially, the paper demonstrates a simple application for student monitoring, capable of recording each student's check-in and check-out times.
• The paper highlights the benefits of such a system and details the components used for construction.

Process Modelling

The research advances by numerically modelling the functioning of the RFID module, examining performance both with and without tags and cards nearby. Special attention is given to how the positioning of tags affects the active tag antenna's characteristics.

Findings and Effects on Human Health

The final section centers on the influence of the RFID tag's proximity to human tissues. The study investigates whether it is safe to operate RFID devices over prolonged periods, emphasizing potential health impacts from exposure to electromagnetic fields (EMFs) at 13.56 MHz.

Conclusion

This work underscores the importance of evaluating long-term EMF exposure risks near human tissues, informing both application development and safety guidelines for RFID technology use. The study reinforces the direct connection between electromagnetic field exposure and possible health outcomes, warranting careful consideration and additional scientific attention.
