In-Depth Understanding of NFC Technology

NFC operates on the principle of electromagnetic induction, enabling data exchange and device interaction between two devices placed in close proximity. Smartphones equipped with NFC antennas can communicate with NFC-enabled accessories, point-of-sale terminals, and even other NFC-enabled phones. This technology is governed by a set of standards known as ISO 14443 and operates at a frequency of 13.56 MHz.
