The retail, security, transportation, manufacturing and shipping industries are all testing or starting to implement sophisticated RFID applications.

Controversy has already erupted: in mid-2003 two major retailers--Wal-Mart in the U.S. and the international clothing maker Benetton--canceled large-scale tests of in-store RFID-centered inventory control systems apparently partly as a response to public reactions that raised the specter of wholesale monitoring of citizens through tags embedded in consumer products.
