28、 without license from IHS-,-,-ivForeword (This foreword is not part of American National Standard ANSI INCITS 256-2007.)BSR INCITS 256 defines a Radio Frequency Identification (RFID) standard for itemmanagement. This standard is intended to allow for compatibility and to encourageinteroperability of

29、 products for the growing RFID market in the United States. SinceU.S. FCC regulations do not restrict physical configuration options, this standard isan enabling standard which supports and promotes several RFID implementationswithout making conclusions about the relative technical merits of any ava

They should be sent to InterNational Committee for InformationTechnology Standards (INCITS), ITI, 1250 Eye Street, NW, Suite 200, Washington,DC 20005.This s
