Before the employment of the new Casio IT-600 series PDA, the handheld terminal they had used was obsolete in hardware, the price and maintenance cost was high. It also had a high rate of failure that often disturbed the daily meter reading and billing process. Needless to say that it caused the firm to struggle to fight against money drawn for the maintenance. The software integrated in the terminal was also obsolete. It was DOS-based.

The Casio IT-600 is more cost-effective and has better specifications and several improvements over the legacy handheld terminal that the electric power company had used. It is also light in weight, user friendly with the integrated GUI interface and touch screen while the robustness is not sacrificed. With a Bluetooth portable printer configured with the IT-600, bills can be issued easily to customers in short time. The wireless communication in Bluetooth between the IT-600 and bill printers and PCs provides the convenience and efficient operation.
