In this paper, the authors present the principles of a low-cost Internet-based data processing system. The main h e a r t of the system is an embedded hardware (ARM 9) running with a Linux OS. The embedded device communicates through General Packet Radio Service (GPRS) module, which makes it accessible from anywhere in the world. The GPRS module provides a bidirectional real-time data transfer between the server and client. The proposed system will provide no need for server software and maintenance. This project can be implemented to any real time application so as to retrieve information from a data source of the server system using GPRS module, and send a file to the remote server through any GPRS enabled mobile device.
