suggest me the technique for communication.

I plan to make an automated menu and billing system for hotels. There will be handheld panels on each table, the data from which should be transfered to the counter along with table identification so that billing could be possible through computer. So I want to know which technology of communication should I prefer, or may be bluetooth, if range I require should be 5 to 10m. This is our final year engineering project, so please suggest me a minimum cost solution to this. Also suggest whether this idea is good or should search some other project.

The best technology suiatable for the project is Bluetooth. It is not too costly.
