Mobile data storage device, particularly passive energy mobile data storage device for use as wireless smart card, comprises coil with connected power supply unit for inductive energy coupling, and controller for controlling functionality

摘要

The mobile data storage device (11) comprises a coil with a connected power supply unit (12) for inductive energy coupling, a non-volatile data memory (15), and a controller (13) for controlling the functionality of the portable data storage device. The portable data storage device has a low rate radio interface with a primary transmission rate and a high rate radio interface (14) with a secondary transmission rate. The secondary transmission rate is higher than the primary transmission rate. The low-rate radio interface is connected with the controller. The controller is configured to receive commands from a remote station outside the data storage device through the low rate radio interface. An independent claim is included for a method for operating a mobile data storage device.
