Off-line mobile payment method

Abstract

The invention discloses an off-line mobile payment method, which comprises the following steps of: a mobile payment device sends dynamic magnetic stripe information which contains an account identification code and a dynamic code to a POS (Point Of Sale) terminal; the POS terminal decodes the dynamic magnetic stripe information to generate a payment message, and sends the payment message to a POS operator; the POS operator sends the payment message to a payment network; the card issuer of the payment network calculates the payment message which contains the account identification code and the dynamic code, and adopts an algorithm which is the same with an algorithm used for generating the dynamic code by the mobile payment device to verify the dynamic code, settlement can be carried out after the dynamic code passes verification, and a settlement message is returned to the POS operator; and the POS operator sends the settlement message to the POS terminal. The dynamic magnetic stripe information in two magnetic tracks of a bank card is transformed, so that the information of the bank card adopted for payment is the dynamic magnetic stripe information of one-time one-password property when the user carries out payment by the mobile payment device so as to improve payment safety.
