The project gives solution by making the hardware connect to the server
And data exchange takes place. The project proposes a system, where the ?les are uploaded from the Raspberry Pi to the server through generated URL and the same ?le can be downloaded from another. Raspberry Pi through a different URL is generated in that hardware device. The LCD display gives indication about the hardware is working properly or not. The RFID reader reads the card number and if the card number is valid then only the data will be sent. This provides the security of the system.
