The acronym 'NFC' stands for Near Field Communication. This wireless technology enables short-range communication between devices, typically within a few centimeters. NFC is widely used in mobile payment systems, allowing users to make transactions by simply tapping their smartphones on compatible terminals. In addition to payment functions, NFC facilitates data transfer, ticketing, and smart card applications. The convenience and security that NFC offers make it an integral part of modern digital payments and contactless technology, enhancing user experiences in purchasing and information exchange.
