associated with electronic passports and are examining security controls to mitigate such risks. EPCglobal's Gen2 standard includes privacy-related guidelines for the use of RFID-based EPCs. The Guidelines on EPC Usage for Consumer Products were adopted as a basic framework for responsible use and deployment of EPC (see WWW. epcglobalinc.org/public_policy/public_policy_guidelines.html) These guidelines include the requirement to give consumers clear notice of the presence of EPCs and to inform them of the choice they have to discard, disable, or remove EPC tags. It is crucial that we ensure that RFID technology is used to improve our lives and our business practices without intruding on privacy. To this end, governments, the private sector, and other agencies must safeguard principles of informed con- sent, data confidentiality, and security; courts and governments around the world are now in the process of determining related legal issues. The Electronic Privacy Information Center (EPIC) has a great deal of additional information about RFID privacy as well as interesting projects on its Web site (www.epic.org/privacy/rfid). The Future of RFID It appears that RFID is well on its way to becoming a large part of our lives. More than 1.3 billion RFID tags were produced in 2005, and that figure is expected to soar to 33 billion by 2010 (In-Stat, "RFID Tags and Chips: Opportunities in the Second Generation," www.instat.com, January 18, 2006). Production will vary widely by industry segment for several years. For example, RFID has been used in WPANs automotive keys since 1991, with 150 million units now in use. This quantity greatly exceeded other segments until recently. By far the biggest RFID segment in coming years will be supply-chain management. Wal-Mart, the world's largest retailer, has spurred this projected growth by mandating that its top 100 (and then its top 300) suppliers use RFID at the pallet/case level. The spread and use of RFID in most sectors will be largely determined by cost, and the costs of RFID
