NFC Near Field Communication ( NFC ) is a wireless technology that enables devices to communicate and exchange data over short distances, typically a few centimeters. NFC technology is used primarily in smartphones, tablets, payment systems, and other smart devices for quick and convenient data transfer, secure payments, and device pairing. Here’s a comprehensive look at what NFC is, how it works, and where it’s used today. How NFC Works? NFC operates on a principle of electromagnetic induction. It uses a specific radio frequency, 13.56 MHz, allowing data transfer between two compatible devices when they are in close proximity (within about 4 cm or 1.5 inches). NFC can be either active or passive: Active NFC devices (like smartphones) can both send and receive data. Passive NFC devices, such as NFC tags, can only send data. These tags are often embedded in products, cards, or even posters and are commonly used to store small amounts of information. Communication between NFC-enabled
