ISO/IEC 15962:2013

Information technology — Radio frequency identification (RFID) for item management — Data protocol: data encoding rules and logical memory functions

The data protocol used to exchange information in a radio frequency identification (RFID) system for item management is specified in ISO/IEC 15961 and in ISO/IEC 15962:2013. Both International Standards are required for a complete understanding of the data protocol in its entirety; but each focuses on one particular interface: ISO/IEC 15961 addresses the interface with the application system. ISO/IEC 15962:2013 deals with the processing of data and its presentation to the RF tag, and the initial processing of data captured from the RF tag. ISO/IEC 15962:2013 focuses on encoding the transfer syntax, as defined in ISO/IEC 15961 according to the application commands defined in ISO/IEC 15961. The encodation is in a Logical Memory as a software analogue of the physical memory of the RFID tag being addressed by the interrogator. ISO/IEC 15962:2013 defines the encoded structure of object identifiers; specifies the data compaction rules that apply to the encoded data; specifies a Precursor for encoding syntax features efficiently; specifies formatting rules for the data, e.g. depending on whether a directory is used or not; defines how application commands, e.g. to lock data, are transferred to the Tag Driver; specifies processes associated with sensory information and the transfers to the Tag Driver; defines other communication to the application.

Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical
Commission) form the specialized system for worldwide standardization. National bodies that are members of
ISO or IEC participate in the development of International Standards through technical committees
established by the respective organization to deal with particular fields of technical activity. ISO and IEC
technical committees collaborate in fields of mutual interest. Other international organizations, governmental
and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information
technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1.
