30、All rights reserved 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 Stan
31、dards 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
32、 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. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of the joint technical committee
33、is to prepare International Standards. Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International Standard requires approval by at least 75 % of the national bodies casting a vote. Attention is drawn to the pos
34、sibility that some of the elements of this document may be the subject of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights.

36、-,-,- ISO/IEC 15962:2004(E) ISO/IEC 2004 All rights reserved vii Introduction The technology of Radio Frequency Identification (RFID) is based on non-contact electronic communication across an air interface. The structure of the bits stored on the memory of the RF tag is invisible and accessible bet
37、ween the RF tag and the interrogator only by the use of the appropriate air interface protocol, as specified in the different ISO/IEC 18000 parts. The transfer of data between the application and the interrogator in open systems requires data to be presented in a consistent manner on any RF tag that
38、 is part of that open system. Functional commands from the application and responses from the interrogator also require being processed in a standard way. This is not only to allow equipment to be interoperable, but in the special case of data carrier, for the data to be encoded on the RF tag in one
39、 systems implementation for it to be read at a later time in a completely different and unknown systems implementation. The data bits stored on each RF tag must be formatted in such a way as to be reliably read at the point of use if the RF tag is to fulfil its basic objective. The integrity of this
40、 is achieved through the use of a data protocol as specified in ISO/IEC 15961 and this International Standard. Manufacturers of radio frequency identification equipment (interrogators, RF tags, etc) and the users of RFID technology require a publicly available data protocol for RFID for item managem
41、ent. ISO/IEC 15961 and this International Standard specify this data protocol, which is independent of any of the air interface standards defined in the various parts of ISO/IEC 18000. As such, the data protocol is a consistent component in the RFID system that may independently evolve to include ad
42、ditional air interface protocols The transfer of data to and from the application, supported by appropriate commands is the subject of the companion standard: ISO/IEC 15961. This International Standard specifies the overall process and the methodologies developed to format the application data into
43、a structure to store on the RF tag.

45、SO/IEC 2004 All rights reserved 1 Information technology Radio frequency identification (RFID) for item management Data protocol: data encoding rules and logical memory functions 1 Scope The data protocol used to exchange information in an RFID system for item management is specified in ISO/IEC 1596
46、1 and in this International Standard. 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. This International Standard deals with t
47、he processing of data and its presentation to the RF tag, and the initial processing of data captured from the RF tag. This International Standard focuses on encoding the transfer syntax, as defined in ISO/IEC 15961 according to the application commands defined in that International Standard. The en
48、codation is in a Logical Memory as a software analogue of the physical memory of the RF tag being addressed by the interrogator. This International Standard 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
