摘要： Provided is a dongle that is connected to a portable terminal for providing a mobile banking transaction service with a banking equipment that includes a banking transaction unit for providing a mobile banking transaction service with a banking equipment; an FM transmitter for outputting a sound source played in a portable terminal through a speaker of an external FM receiver; a charger for receiving an external voltage to charge the portable terminal; and a connector to be connected to the portable terminal simultaneously or individually in order to perform functions of the banking transaction unit, the FM transmitter, and the charger. The banking transaction related components are implemented with a single separate device, i.e., dongle, and can be mounted when necessary. Therefore, a separate banking related module (software and/or hardware) is unnecessary, thereby slimming the portable terminal. In addition, the convenience of the banking transaction is improved because the dongle can be applied to general terminals having a minimum software specification.

摘要翻译： 提供一种连接到便携式终端的加密狗，用于向银行设备提供移动银行交易服务，所述银行设备包括用于向银行设备提供移动银行交易服务的银行交易单元; FM发送器，用于通过外部FM接收器的扬声器输出在便携式终端中播放的声源; 用于接收外部电压以对便携式终端充电的充电器; 以及要连接到便携式终端的连接器，以便执行银行交易单元，FM发送器和充电器的功能。 与银行交易相关的组件通过单个独立设备（即，加密狗）实现，并且可以在必要时被安装。 因此，不需要单独的银行相关模块（软件和/或硬件），从而使便携式终端变薄。 此外，由于加密狗可以应用于具有最小软件规格的一般终端，所以提高了银行交易的便利性。
