Procter & Gamble's Chief Privacy Officer, Sandy Hughes, has contributed to a forthcoming book (July 8) : RFID: Applications, Security and Privacy, edited by Samuel Garfinkel and Beth Rosenberg. I have the book on order, but based on the extensive excerpt at the Amazon post above, it contains a good overview of the technology and the issues it raises, with lots of examples. The excerpt serves as a nice introduction to the topic.
