what is nfc in mobile

NFC stands for Near Field Communication, which is a set of short-range wireless technologies that allow devices like phones and smartwatches to exchange small bits of data with other devices and read NFC-equipped cards over relatively short distances. NFC transmissions are short range and require the devices to be in close proximity, typically within 4cm or less to initiate a connection. Android-powered devices with NFC simultaneously support three main modes of operation: reader/writer mode, P2P mode, and card emulation mode. NFC can be used for a variety of purposes, including mobile payments, exchanging digital content, and connecting electronic devices with a touch. The most common use of NFC technology in smartphones is making easy payments with mobile payment services like Samsung Pay, Google Pay, and Apple Pay. NFC can also be used to quickly connect with wireless devices and transfer data with Android Beam.
