RFID firewalls are here !

Today I read an Ars Technica article about a new protection for your RFID tags (you know, those tags that are now used for taking stock of inventory, theft protection, and are now showing up in passports).

What great about this new protection is that you can configure which tags you want to allow to be queried – you can even select trusted readers, for example if you have an RFID chip in your card that allows you access to your work building, you can allow that reader to query that tag, but no others.

So far it’s still in development, but if and/or when RFIDs become more and more pervasive, this will come in useful.
