<p>Every year more than 6000 thefts, to a value of 1.5 billion SEK, are reported</p><p>within the Swedish building trade. Plus all the indirect costs of having the</p><p>construction site standing still.</p><p>SafeTool is a newly started company that will try to prevent this problem with</p><p>a modern technology solution.</p><p>The key to SafeTool’s solution is RFID – Radio Frequency Identification – and</p><p>the solution looks like this;</p><p>All tools are stored in a container on the construction site. Every tool is</p><p>equipped with a RFID-tag that uniquely identifies the tool. With antennas in the</p><p>container it is possible to detect when a tool is leaving the container and when</p><p>it comes back. Every worker must wear a RFID-tag so it will be possible to see</p><p>who was taking the tool out of the container. The container has no external</p><p>locks on it, but the RFID-tag works as a key. An antenna on the roof of the</p><p>container identifies the worker and automatically unlocks the door.</p><p>All the tool and personnel traffic through the door of the container are reported</p><p>to a central server via GPRS. The server stores all info in a database. The</p><p>administration of the system will be done through a website.</p><p>This paper will show how we made this solution work in practice. How we</p><p>created and programmed the client and server and the protocol that makes them</p><p>understand each other.</p>
