RFID Guardian Protects Your Privacy
An anonymous reader writes "A new device devised by Amsterdam graduate student Melanie Rieback is designed to serve as a portable firewall for RFID tags. The portable battery-powered RFID Guardian uses an access control list to filter RFID queries, blocking queries that aren't approved. Rieback, who is also known for being the first researcher to develop a proof of concept RFID virus, hopes to offer version 3.0 of the RFID Guardian to the public at cost."
I've found an even simpler RFID blocking solution.
The genius part was proving their was a threat, then inventing the solution to that threat.
Fantastic business model.
