NFC Technology, or Near Field Communication, is a short-range wireless communication technology that allows devices to exchange data when they are close to each other, typically within a few centimeters. It is commonly used in mobile payments, where smartphones can securely transmit payment information to point-of-sale terminals, making transactions quick and convenient. In addition to payments, NFC Technology is also used for sharing files, connecting devices, and accessing information. For example, tapping a smartphone against an NFC-enabled poster can provide instant access to a website or app. This technology is widely integrated into smartphones, smartwatches, and various other devices.
