Abstract: The present invention discloses an expansion structure for an electronic card for installing the electronic card. The expansion structure includes a carrier board, a limiting member and a fixing element. The carrier board carries the electronic card. The limiting member includes a sidewall and a blocking piece extended from the sidewall, the sidewall is formed on one side of the carrier board, and the sidewall, the blocking piece and the carrier board jointly define a sliding channel for accommodating the electronic card. The fixing element fixes the electronic card at the carrier board. Thus, a small-size electronic card can be installed on an installation interface of a large-size electronic card by the expansion structure, achieving the effect of sharing the same installation interface.

Abstract: A dock adapted to connect to a portable electronic device is provided. The portable electronic device has a first antenna signal transceiving mode and a second antenna signal transceiving mode. The portable electronic device switches from the first antenna signal transceiving mode to the second antenna signal transceiving mode when a magnetic sensor of the portable electronic device senses the presence of a magnetic force. The dock includes a base, back support element, limit component and magnetic component. The base has a connection surface which the limit component faces. Two ends of the back supporting element adjoin the base and the limit component, respectively. The magnetic component is disposed on the connection surface and generates the magnetic force. The portable electronic device is placed between the connection surface, back supporting element and limit component.

Abstract: A system performs cooperative personalized promotion based on consumer-store interactive transaction history at multiple stores of different categories. The system includes a cooperative personal promotion platform. The cooperative personal promotion platform is provided for multiple stores of different categories to register a number of promotion information and to display at least one preferential-combination-information constituted by the promotion information. The promotion platform includes a data exchange interface, a remote-end server and a consumer record unit. The data exchange interface is used for reading a consumer's basic information into the platform, and connecting to the remote-end server via a network. The remote-end server is used for checking the consumer's basic information and recording consumer's latest interactive transaction in the consumer record unit for updating a consumer-store interactive transaction history.
