Telecoms Korea reports that the South Korean government, through its Ministry of Information Communication, is working on guidelines for RFID privacy protection:
The guidelines ban storing personal information on RFID tag against related laws or without clear statement of consent from the person in question. Furthermore, RFID-tagged products should be indicated with proper mark accompanied by methods of removing the tag. To install a RFID reader, you have to inform shoppers or customers of the fact.
Implanting RFID tags in human body or attaching them to any goods without users’ notice is prohibited, unless otherwise stated by specific provisions of the law.
Such guidelines all but obviate the use of RFID as an anti-theft measure in consumer retail, one would think, but do address the primary consumer privacy concerns.
