Abstract: Disclosed embodiments include an NFC payment method and apparatus implemented on a mobile terminal. In some embodiments, an NFC payment function of a mobile terminal is activated; an NFC connection to a POS terminal is directly established in an inactive-screen state, so as to start the current payment process; payment authentication is performed on a user, so as to instruct the POS terminal to make a payment when the authentication is completed. Some embodiments of the present disclosure provides a more convenient and efficient NFC payment manner. In some embodiments, the system can directly invoke NFC quick payment in an inactive-screen state, which significantly reduces an operation time and operation cost of a user. Moreover, the user may need to be authenticated before the payment, which also guarantees the security of the payment. Therefore, some embodiments of the present disclosure provides better mobile quick payment experience for the user.
