Abstract :

              In this project, a data transfer between pen drive to pen drive and pen drive to mobile without using a computer or laptop is discussed. A data transfer is done by using a computer or laptop  means  it  consumes  more  power  and  it  is  not  a handy  device  to  carry  to  particular locations. To overcome this , a data transfer is done by using an ARM processor (handy device). A pen drive is inserted into the USB port then a signal will be sent to the ARM processor. By using this signal processor identifies the host pen drive is detected . Now the ARM processor will  start  fetching  the  data  from  the  source  pen  drive  into  the  buffer  and  the  ARM  processor waits  for  the  signal  from  the  destination  pen  drive.  When the ARM processor gets the signal from the slave pen drive, the ARM processor is ready to transfer the data. Before transferring a data the ARM processor should get the input from an external touch panel from the user . Once the user press the touch panel the arm processor gets the information to transfer the data between two pen drives.

Existing System :

• It is not always possible to carry the laptops or computer to particular locations.
• High power consumption
• The threat of viruses has made the computer to more complicated

Proposed System :

• Computers and laptops are not used, so no threat of viruses.
• Small and handy device to transfer a data between pen drive to pen drive and pen drive to mobile by using ARM processors
• Low power consumption
