The advantages of NFC include convenience, security, versatility, and low power consumption.
NFC: Near Field Communication Technology
Near Field Communication (NFC) is a Contactless communication technology that allows two devices to exchange data within extremely short distances (usually less than 10 cm).
How NFC works
NFC technology is based on electromagnetic induction, using high-frequency (13.56 MHz) radio waves. When two NFC devices come into proximity, they create an electric field through electromagnetic induction. This electric field can be used to exchange data such as texts, files, contacts and payment information.
Functions of NFC
NFC has the following main functions:
- Data exchange:NFC can be used to A variety of data is exchanged between devices, including text, files, contacts, and calendar information.
