The Palmtec Plutonia is a handheld computer with an integrated printer and PC interface that weighs around 500 grams and runs on a rechargeable battery. It can be used for spot billing tasks like utility billing where carrying a full PC, printer, and UPS is not practical. It has applications in fields like banking, insurance, petrol pumps, and delivery billing. It stores customer data and allows field workers to quickly generate bills on site by entering meter readings. Data is synchronized back to a main office PC daily. The Palmtec Plutonia automates utility spot billing tasks previously done manually with paper, reducing billing time and errors.
