              Near-Field Communication (NFC) is a groundbreaking technology that enables short-range wireless communication between devices. It allows for quick and convenient data exchange, making it an essential part of modern mobile devices and contactless payment systems. NFC operates on the principle of electromagnetic induction, and its ability to provide seamless connectivity has opened up a wide array of applications across various industries.<\/p>"},{"question":"How did Near-Field Communication (NFC) originate?","answer":"

              The concept of NFC can be traced back to the early 1980s when researchers at the Radio Corporation of America (RCA) explored the possibilities of using magnetic induction for secure data transfer. However, it wasn't until 2002 that the term \"Near-Field Communication\" was coined, thanks to a collaboration between Sony and Philips. The first commercial use of NFC technology emerged in 2004 when Nokia introduced NFC-enabled phones.<\/p>"},{"question":"How does Near-Field Communication (NFC) work?","answer":"

              NFC relies on electromagnetic induction to establish a communication link. The active device (initiator) generates an alternating current in its NFC antenna, creating an electromagnetic field. When a passive device (target) comes within the range of this field, it induces a current in its own NFC antenna, allowing data exchange to take place. The data transmission occurs at a rate of up to 424 kbps, making it suitable for various applications.<\/p>"},{"question":"What are the key features of Near-Field Communication (NFC)?","answer":"
