| Summary: | Barcode system is a very common system that is widely used in various areas in today businesses. Pocket Barcode application will be another key evolution for barcode. Pocket barcode application that uses wireless network like WIFI is able to enable barcode to be captured anywhere and extract the information on the fly from server located somewhere else within the WIFI coverage area. Besides that, it can save computation time of Personal Digital Assistance (PDA) and at the same time utilize PDA (client) to communicate with PC (server) for more accurate information like inventory, delivery and pricing of stocks. The image captured by PDA is transferred back to server for processing and data extraction. In this project, client and server programming model was used to program the “Pocket Barcode Reader� client and “Pocket Barcode Server� applications. Actual data is transferred using WIFI network from client to server and vice versa through asynchronous socket. The asynchronous socket used transmission control protocol (TCP) to transmit data. Microsoft C# 2005 language was used to program both applications. Microsoft Windows Mobile 5.0 Software Development Kits was used to simulate “Pocket Barcode Reader� client application. The result obtained from this project is client program (Pocket Barcode Reader) that is able to transmit barcode pictures to server program (Pocket Barcode Server) for real time decoding. The decoded result is then transmitted back to client program for display. |
