Gen 2

An organization called EPCglobal is working on an international standard for the use of RFID and the Electronic Product Code (EPC) in the identification of any item in the supply chain for companies in any industry, anywhere in the world. The organization's board of governors includes representatives from EAN International, Uniform Code Council, The Gillette Company, Procter & Gamble, Wal-Mart, Hewlett-Packard, Johnson & Johnson, Checkpoint Systems and Auto-ID Labs. Some RFID systems use alternative standards based on the ISO-classification 18000-6.

The EPCglobal gen 2 standard was approved in December 2004, and is likely to form the backbone of RFID tag standards moving forward. This was approved after a contention from Intermec that the standard may infringe a number of their RFID related patents. It was decided that the standard itself did not infringe their patents, but it may be necessary to pay royalties to Intermec if the tag was to be read in a particular manner. EPC Gen2 is short for EPCglobal UHF Generation 2.

Patient identification

In July 2004, the Food and Drug Administration issued a ruling that essentially begins a final review process that will determine whether hospitals can use RFID systems to identify patients and/or permit relevant hospital staff to access medical records. The use of RFID to prevent mixups between sperm and ova in IVF clinics is also being considered [2]  (http://www.newscientist.com/article.ns?id=dn7209).

Also, the FDA recently approved the country's first RFID chips that can be implanted in humans. The 134.2 kHz RFID chips, from VeriChip Corp., a subsidiary of Applied Digital Solutions Inc., can incorporate personal medical information and could save lives and limit injuries from errors in medical treatments, according to the company. The FDA approval was disclosed during a conference call with investors.

Some in-home uses, such as allowing a refrigerator to track the expiration dates of the food it contains, have also been proposed, but few have moved beyond the prototype stage.
