The term "near field communication" (NFC) refers to a set of communication protocols that enable two electronic devices to exchange data when placed within close proximity, typically within a few centimeters. NFC technology is commonly used for contactless payments, where users can simply tap their device to make transactions. Additionally, NFC facilitates quick pairing between devices, such as connecting smartphones to speakers or transferring files. Its convenience and efficiency have made it a popular choice in modern consumer technology.
