RFID Guardian started as a research project by Melanie Rieback from VU Amsterdam. Its goal was to create a 'RFID firewall'. After much research, prototype boards, and you name it several people have joined the project leading the project into:

The namesake of our project is the RFID Guardian: a mobile battery-powered device that offers personal RFID security and privacy management. One the focuses of our project is to build an RFID Guardian prototype.

Our group also performed the first-ever research on RFID Malware.

Also, Do you want to beta-test a copy of our RFID Guardian HW? If so, please add yourself to the mailing list of people we will notify when we start to mass-produce and distribute the HW, or send us an email at info@rfidguardian.org.

The hardware is open source.

They're working on interfaces to speak to the Guardian, and Symbian S60 is one of them. However, an interface for Maemo might be interesting.
