Near Field Communication (NFC) is a short-range wireless communication technology that enables two devices, such as smartphones or contactless payment systems, to exchange data when they are placed close to each other, typically within a few centimeters. NFC technology is widely used in mobile payments, such as Apple Pay and Google Wallet, as well as in transportation systems, access control, and smart devices. NFC operates at a frequency of 13.56 MHz and supports both read/write operations and peer-to-peer communication. Its convenience, security features, and ease of use have made it a popular technology in various industries, particularly for secure transactions.
