Abstract: Apparatus and methods for binding a wearable device for use with the wearable device, a terminal, and a server are presented. The method executed by the wearable device includes providing device information to the terminal, receiving a device certificate from the server, and storing the device certificate for performing payment using the corresponding user account. The method executed by the server includes receiving a binding request from the wearable device via the terminal, generating a device certificate of the wearable device based on the device identification, and providing the device certificate to the wearable device. The method executed by the payee device includes acquiring a transaction certificate of a wearable device and sending a payment collection request to a server including the transaction certificate of the wearable device and payment sum information.

Abstract: A sensor device is for detecting metal. The sensor device may have a substrate, an electrode on the substrate, and a biopolymer-metal composite film on the electrode. The biopolymer-metal composite film may include a metal and a biopolymer. The sensor device may further have circuitry coupled to the electrode and configured to apply a sensing signal to the electrode.

Abstract: An intelligent terminal scans, as a scanned identification code, an identification code that is displayed by an intelligent wearable device. A wireless broadcast signal is transmitted by the intelligent terminal to identify the intelligent wearable device. A response to the wireless broadcast signal is received by the intelligent terminal and from the intelligent wearable device, where the response includes an identification code. The identification code is extracted by the intelligent terminal from the response and as an extracted identification code. The intelligent terminal compares the scanned identification code and the extracted identification code. If it is determined that the scanned identification code and the extracted identification code are the same, the intelligent terminal is paired with the intelligent wearable device.

Abstract: A request is received from an intelligent terminal by an intelligent wearable device for enabling a one-time password function, and the intelligent wearable device is configured with an embedded algorithm chip. Provisional data from a provisioning server is obtained using the intelligent terminal. The provisional data is verified. If the provisional data is verified, the verified provisional data is stored on the intelligent wearable device. Using a micro operating system, the embedded algorithm chip is invoked to generate a one-time password, and the one-time password is displayed on a computer display of the intelligent wearable device. The one-time password is configured to permit a verification server to verify the intelligent wearable device.

Abstract: The present application discloses a server load balancing method and apparatus, and a server device. The method includes: classifying, according to link quality of back-end servers in a server cluster, the back-end servers into multiple server groups; setting priorities of the multiple server groups according to link quality of the server groups; selecting, when an access request sent by a first terminal is received, a server group from the multiple server groups as a target server group based on the priorities; selecting a target back-end server from the target server group; and establishing communication between the target back-end server and the first terminal.
