Cloud-based RFID; A privacy crawler?

It is always about the cost factor for companies. But, it maybe partly due to technology trend as well. In Australia, the proposition to design a cloud-based RFID was mooted. I am unsure whether the idea has been translated into a proof of concept. If it has, it maybe a privacy crawler, especially, at this point of time - where people around the world has been advocating on cloud computing's chief issues: security, data protection and privacy.
