Bluetooth tracking

We are looking to use people's mobile phone bluetooth ID's to track visitors to our venues. Using a Windows based machine in each venue we would like to scan for bluetooth phones in each venue once a minute. The length of each visitors stay should be logged, as should movement from venue to venue. Each windows machine will be connected to the internet and results are to be sent in real time to a hosting account. This should allow records of visitors to each venue to be displayed and printed from a password protected website. It should also be able to show movement of visitors between venues. ## Deliverables We would like to be able to increase the number of venues at any time, adding them through the web interface on the server and installing the software onto a Windows XP machine and placing it into the venue. It would also be? useful? to seporate venues into areas (e.g. which town each venue is in). Please feel free to ask any more information you require.
