Near Field Communication (NFC) is a short-range wireless technology that allows devices to communicate with each other when they are in close proximity, typically within a few centimeters. It operates at a frequency of 13.56 MHz and is based on RFID technology. NFC enables contactless communication between devices, such as smartphones, tablets, and smartwatches, making it convenient for various applications like mobile payments, access control, smart advertising and data transfer. The technology is secure and widely used in industries like retail, transportation, and healthcare. NFC has revolutionized the way we interact with our devices and has opened up new possibilities for seamless connectivity.
NFC tags are small and usually passive devices that can store and transmit information wirelessly. They work on the principle of NFC technology. NFC tags can be programmed with various types of information, such as URLs, contact information, or even commands to perform certain actions on a device.
