I would suggest you start out by looking at the gumstix
(http://www.gumstix.org/) for the host computer.

But it could cost hundreds maybe a thousand euro to setup the system,

My experience on this topic is mostly with experimenting with RFID cards
and RFID reader. I've got a couple of readers the open source OpenPCD
(http://www.openpcd.org/) and two CardMan devices bought from
(http://www.cryptoshop.com/).
If your around this Friday evening why not to the Dublin 2600
(http://dublin.2600.ie/) meeting. I'll be there and can bring along
some of my RFID hardware and we could talk about it in more detail.
