Abstract: A computer server receives a payment request including a payment order sent by a first mobile 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 mobile client device. The first mobile client device generates an audio signal associated with the response and broadcasts the audio signal including the first payment identifier. The computer server receives a collection request including a second payment identifier and payee information from a second mobile client device. The collection request was generated by the second device in response to a detection of the audio signal broadcasted by the first mobile 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 device.

Abstract: A computer server receives a payment binding change request submitted by a client application from a requesting terminal, where the payment binding change request carries a payment account and terminal identification information of a target payment-bound terminal. If the target payment-bound terminal is registered as a secondary payment-bound terminal of the payment account, the computer server sends verification information to the target payment-bound terminal and returns prompt information to the client application. The prompt information is used to prompt a user of the client application to input and return the verification information sent to the target payment-bound terminal. If the verification information returned by the client application matches the verification information sent to the target payment-bound terminal, the computer server sets the target payment-bound terminal as a primary payment-bound terminal of the payment account.

Abstract: The present invention provides a Suspended Wheel Reducer and a suspended wheel crossing-zero multilevel transmission, both of which comprise a front planetary gear train, a rear planetary gear train and a suspended wheel. With different design for the dimension of the gear wheels contained in the front planetary gear train, the rear planetary gear train and the suspended wheel, it's possible to achieve optional different reduction ratios. The Suspended Wheel Reducer and the suspended wheel crossing-zero multilevel transmission have simple configuration, higher reliability, thus overcoming the drawback in prior art, in which a transmission mechanism for multilevel gear shift mechanism is required to achieve greater reduction ratio, reducing its overall dimensions and cost.

Abstract: The present application relates to a method for making payments using a mobile terminal having one or more processors, memory storing program modules to be executed by the one or more processors, and one or more movement sensors for detecting user gestures of moving the mobile terminal. The mobile terminal receives a payment request from a remote server. In response to the payment request, the mobile terminal detects a gesture motion of the mobile terminal using at least one of the movement sensors and compares the gesture motion with a plurality of predefined gesture motions. If the gesture motion satisfies a predefined mobile payment gesture motion, the mobile terminal then sends an authorization instruction to the remote server. The remote server then arranges a payment to a payee associated with the payment request in accordance with authorization instruction.
