I. Introduction
Near-field communication (NFC) has now become a critical data exchange approach in wireless communication, which has widespread adoption in industries and people's daily lives. The COVID-19 pandemic has been further accelerating such contact-free communication in commercial scenarios in terms of packaging, tracking, and anti-counterfeiting [1]- [3]. The global NFC market size was valued at 15 billion in 2019 and is estimated to experience significant growth and reach over 54 billion by 2028 [4], [5]. Such prosperity of the NFC market facilitates its versatility for more commercial use.
