A computer server receives a payment request including a payment order sent by a first client device.In response,the computer server allocates a first payment identifier to the payment order and returns a response including the first payment identifier to the first client device. The first client device broadcasts an audio signal associated with the response and the audio signal includes information of the first payment identifier. Subsequently,the computer server receives a collection request including a second payment identifier and payee information from a second client device. The collection request was generated by a second client device in response to a detection of the audio signal broadcasted by the first client device. If the second payment identifier corresponds to the first payment identifier,the computer server then processes the payment order using the payee information and sends a payment completion message to the first client device. |
