Story: RFID blocker may ease privacy fears

•

RFID blocker - RFID tags would be useless at checkout unless you turn it off. Then (at possibly the worst point with regard to commercial privacy) all RFID tags in your closthing etc. can be read along with your new purchases. The technology also open to smarter readers that can listen through the noise.

The only acceptable (privacy wise) solutions are:
* Zap the tag completely.
* Delete the unique ID from each tag as the goods are purchased. This allows "washing instruction" type applications to still work. (Even then a combination of anonymised tags could be used to track a person on a given day).
* As has been suggested elsewhere - 10 second burst of full power in a microwave!
