Mobile payment method integrating financial card payment and settlement

Abstract

The invention discloses a mobile payment method integrating financial card payment and settlement. The method comprises the following steps that an HCE (Host Card Emulation) application loaded in a mobile terminal generates a payment message used for payment by a payment message generation algorithm according to a payment mark and a storage payment key, and sends the payment message to a POS application loaded in the mobile terminal; the POS application generates a POS message used for settlement by a POS message generation algorithm according to the received payment message and a stored POS key, and sends the POS message to a payment network through a POS operator; and the payment network performs settlement according to the received POS message and returns a settlement message to the POS application. According to the method, the HCE application and the POS application are integrated in the mobile terminal, so that a user can perform the step of emulating ''card swiping'' on the mobile terminal without a third-party payment platform, and a payment process is securer and more reliable; and the mobile terminal does not need to be configured with a security element, so that the application range is wide.
