The technology that supports mobile payments through smartphones is known as near field communication (NFC). This wireless communication technology enables smartphones to exchange data with payment terminals when in close proximity, facilitating fast and secure transactions. NFC is commonly used in mobile wallets like Apple Pay and Google Pay, allowing users to make purchases simply by tapping their devices on compatible terminals. Additional security measures, such as tokenization and biometric authentication, further enhance the safety of mobile transactions. NFC technology has revolutionized the payment landscape, providing convenience and efficiency for consumers and merchants alike.
