Abstract- The aim of this paper is to design a Wireless USB flash
discussed above, by implementing the Bluetooth module in the
drive in which the USB flash drive can be used without
flash drive, the size of the flash drive must not be affected. Hence
connecting using the dongle. This makes the data transfer using
this module is preferred.
USB more sophisticated. It also provides speed upto 1 Mbps

wave of 2.4 GHz is to be produced to synchronize the PC with
Ustorage device by all the people. The main reason for this is the USB flash drive and transfer the data. The module which
because of its compatibility and user friendly memory storage
meets the requirements is IEEE 802.15.4-Compliant Atmel
device. It can able to store data of any kind. The data stored in

USB flash drive. Memory spaces commonly used are 2GB, 4GB,
8GB, 16GB and 32GB. The cost of the USB device varies
depending upon the memory space of the flash drive. The USB
flash drive can be operated by connecting it to a dongle in the PC
or laptop.
Now my paper is about synchronizing the data available in
the USB flash drive with the PC or laptop. This can be achieved
by implementing the effect of few modules available and also by
modifying the design of the USB flash drive. We shall now
discuss in detail
II. MODIFICATIONS TO BE DONE IN THE USB
FLASH DRIVE
A bluetooth module is to be attached to the USB flash drive.
By implementing various technologies, the addition of the
Bluetooth module is made sure that it doesn't affect the size of
the USB flash drive. One of the suggested Bluetooth modules
Figure2: IEEE 802.15.4-Compliant Atmel transceiver
that can be used is Bluetooth V2.0 RS232. The module is shown
in figure.1

TO MAKE THE OPERATION MORE SECURE
During synchronization of data, only the authorized PC user
should access the USB flash drive. Hence, a solution has been
found for this problem. We can use a secure USB flash drive i.e.
a USB flash drive with secure code can be used. It has a keypad
with a numbers from 0 to 9. Unless the correct combination of
the code is pressed, the USB flash drive is inaccessible. Thus
unauthorized members cannot access the USB flash drive. The
USB flash drive with security keypad is shown in figure 3.
Figure1: Bluetooth V2.0 RS232
The reason for preferring this module is because the
dimensions of the module is (2.7cm*1.3cm*0.1cm). As we

gets synchronized with the PC and now it is ready to perform any
type of operation such as copying the files, deleting the files,
editing the files in the memory of the flash drive. The transfer of
data is estimated to about 1 Mbps. It may vary according to the
file size. The operation can also be explained by the following

WORKING OF THE MODULE
As discussed earlier, the USB flash drive is unlocked by
entering the correct combination of the security code. Once it
gets unlocked, the Bluetooth module gets activated. Then
through the PC the RF wave of frequency 2.4 GHz is generated
and is searches for the Bluetooth module. Once we select the
Bluetooth module of the USB flash drive, the USB flash drive
