Abstract

A wireless digital data storage device mounted in a pen shaped housing has a barrel, a reservoir tube assembly and a memory device. The memory device is held in the barrel and the memory device having a controller, a memory unit, a wireless communicating unit and a display. The controller is electronically connected to the memory unit, the wireless communicating unit and the display. The wireless communicating unit is used to link to computer device to transmit data stored in the memory or receive data from the computer device. Therefore, the wireless digital data storage device can be used to access, store and exchange digital data in wireless way and to perform writing function.

Claims
