What is NFC?
NFC allows communication between two electronic devices such as phones, smart watches, etc. placed at very short distances, say up to 10 cm. It enables the exchange of digital content and connects electronic devices. NFC technology also ensures secure transactions. It uses radio waves for transferring data or information from one device to another. Radio waves are a type of electromagnetic radiation with the longest wavelength. To sum up, NFC basically extends RFID (Radio Frequency ID tags) and contactless capabilities with more dynamic features enabled by modern smartphones. The most common applications that use NFC include payment apps like Google Pay or Apple Pay. NFC can complement the existing wireless technologies in the smartphones like Bluetooth, Wi-Fi Direct, etc
Everything You Need to Know About NFC
Communication and data transmission play a vital role in today’s digital era. It makes the transmission of information possible from one device to another and from one place to another. With a large amount being stored and transmitted every day, it requires proper communication protocols. Communication has been evolving constantly. We’ve come a long way from using messengers to wired communications and then to wireless modes. Yet, we still keep advancing in various wireless methods of communication. Wireless communication is the transfer of data eliminating the use of wires and cables. The different types of wireless communications include satellite communication, infrared communication, broadcast radio, microwave communication, Bluetooth technology, etc. One such advanced technique is the Near Field Communication or NFC. NFC is used for the transmission of data using radio waves especially, for shorter distances.
