Blocker Tags to Protect Privacy From RFID Tags

geekee writes "According to an article at CNET, RSA Security is developing a 'blocker' tag that disrupts RFID tag transmissions, protecting a person's privacy from those who would abuse RFID technology. The blocker tag would be embedded in your watch, for instance. This method has an advantage over destroying the RFID tags after purchase because useful information on the tag could help consumers (e.g. laundry instructions)." According to the RSA scientist quoted in the article, privacy concerns regarding RFID have been overblown, but it's still worth being proactive when finding ways to defeat the tags.

Couldn't you use it to block the rfid tags inside the store? Say the one embedded in the package you're shoplifting?
It'll spiral into a build up of detection technology and masking technology. Like the radar gun/detector/jammer industry.
