Traceability is defined in the ISO Regulation 9000:2000 as the ability to trace the history, application and location of what is under consideration. Traceability systems are record keeping systems designed to track the flow of product or product attributes through the production process or supply chain. All international supply chains are forced to comply with traceability requirements. In this project, we develop and implement an end-to-end mobile application that traces the poultry production. The application consists of front-end and back-end systems. At the front-end, the worker uses a handheld device (cell phone, PDA, etc.) to enter and send the information collected at the field to the back-end server. The handheld device should be connected to the GSM (Global System for Mobile Communications) wireless network, and should be GPRS enabled. The back-end server documents all information received from the front-end and make them available, through the Internet, to system administrators. The back-end system consists of web server, application logic and database server.
