Security in Near Field Communication (NFC): Threats, Challenges, and Solutions

Abstract

Near Field Communication (NFC) is proving out to be key technology driving contactless interactions, ranging from mobile payments to secure access control and data exchange. Due to seamless integration of this technology into smartphones, wearables, and IoT ecosystems it has revolutionized user experiences but along with these experiences It has also amplified security concerns due to the nature in which data gets transmitted. This paper provides comprehensive analysis of NFC security in current times. In this paper we have tried to explore advancements in cryptographic protocols, identified key vulnerabilities such as relay attacks and side-channel exploits, and propose some robust countermeasures for such existing threats. This work aims to deliver actionable insights for various stakeholders to enhance NFC’s resilience while promoting trust in its diverse applications.
