The IEC has released ISO/IEC 18000-2:2009, which defines the air interface for radio frequency identification (RFID) devices operating below 135 kHz. The purpose of the standard is to provide a common technical specification for RFID devices that can be used by ISO committees developing RFID application standards. The standard is intended to allow for compatibility and to encourage interoperability of products in the international marketplace.Read a preview of this standard at the IEC Web store.
