"NFC" stands for Near Field Communication in mobile payment systems. This technology enables short-range wireless communication between devices, typically within a distance of a few centimeters. NFC is widely used for contactless payments, allowing users to make transactions simply by tapping their mobile devices against a payment terminal. The secure transfer of information supports various applications, including mobile wallets like Apple Pay and Google Pay. Additionally, NFC enables features such as quick pairing of devices and sharing data, enhancing user convenience and efficiency in daily transactions.
