Mobile payment technologies operate through various methods to facilitate financial transactions via mobile devices. They typically utilize near-field communication (NFC), where users can make payments by tapping their smartphones against a compatible terminal. Additionally, mobile wallets store users' payment information securely, allowing transactions through QR codes or online payment links. These technologies often incorporate encryption and tokenization to protect sensitive data during transfer. Popular platforms like Apple Pay and Google Wallet provide seamless and fast transaction experiences while enhancing user convenience and reducing the need for physical cash.
