An Implementation of Wireless Data Transfer Between Two Pen Drives Without PC Using Raspberry Pi

Abstract

The simple and advancement in the microcontroller Raspberry-Pi and RFID smart card technology provides a total security and automation in distribution of fuel [1]. It is interface with high speed fuel dispenser which is convenient for consumer to operate. In our system the password and IRIS detection will be provided to the user for secure transaction. The customer has to wave the smart card at the reader which has account details displayed on the LCD provided by the fuel station which will help the fuel company to create authentication for user also the distribution of the fuel, this fuel dispense is not possible until it gets verified by the database. In short we provide secure system for fuel distribution. The advancement of this project can help industry financially. In this paper, a data transfer between pen drive to pen drive 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 a Raspberry Pi processor (handy device). A pen drive is inserted into the USB hub then a signal will be sent to the processor. By using this signal processor identifies the host pen drive is detected. Now the processor will start fetching the data from the source pen drive into the buffer and the processor waits for the signal from the destination pen drive. When the processor gets the signal from the slave pen drive, the processor is ready to transfer the data. Before transferring a data the processor should get the input from an external touch panel from the user. Once the user press the button from TFT display unit, the arm processor gets the information to transfer the data between two pen drives.
