Detailed explanation-1: -NFC, which was introduced in the early 2000s, uses a specific RFID frequency (13.56MHz, to be exact) for close-range communications.
Detailed explanation-2: -NFC works based on the principle of near field magnetic communication. This principle of inductive coupling is applied to all communications based on near field magnetism between transmitting and receiving devices.
Detailed explanation-3: -Near-field communication (NFC) is a short-range wireless connectivity technology that uses magnetic field induction to enable communication between devices when they’re touched together or brought within a few centimeters of each other.
Detailed explanation-4: -Today NFC is most commonly used for contactless payment. In addition to smartphones, more and more credit cards and other payment cards feature NFC technology. As a rule banks and credit card companies issue new credit cards exclusively with NFC chips.
Detailed explanation-5: -What is an example of near field communication? An example of near field communication is a contactless payment system, such as Apple Pay or Google Pay. These payment systems use NFC technology to securely and quickly transfer payment information from your device to the merchant’s payment terminal.
