National
12、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. Oth
13、er 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. International Standards are drafted in accordance with the rule
14、s given in the ISO/IEC Directives, Part 2. The main task of the joint technical committee 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 appr
15、oval by at least 75 % of the national bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO/IEC 29133 was prepared by Joint Tech
16、nical Committee ISO/IEC JTC 1, Information technology, Subcommittee SC 31, Automatic identification and data capture techniques. ISO/IEC 29133:2010(E) ISO/IEC 2010 All rights reserved vIntroduction Traditionally, linear bar codes and two-dimensional symbols have been considered as write once/read ma
17、ny times (WORM) technologies. The advent of Rewritable Media, which can completely change the displayed information, provides applications with an opportunity to erase previously encoded data carriers and human readable data and to overwrite this with new data. There is a requirement to ensure that
18、Rewritable Media can be fully integrated with pre-existing WORM applications. Additionally, Rewritable Media can be combined with rewritable RFID (radio frequency identification) technologies to create what is called a Rewritable Hybrid Media product. In this form, the characteristics of the optical
19、 data carrier and RFID data carrier can be used in an integrated manner in business applications. Because the rewriting procedure for each technology is different, there is a requirement to ensure that this data is synchronised, not necessarily to be identical, on each rewriting cycle. Because the R
20、ewritable Media and RFID tags can be re-used for a number of cycles, they can contribute to environmental improvement as they produce a smaller carbon footprint over their lifetime than current systems that use paper and card-based products. Also, by combining Rewritable Media with RFID, the number
21、of single-use RFID labels can be reduced. Manufacturers of bar code equipment and RFID equipment, and the users of both these data capture technologies, require publicly available standard test specifications for the objective assessment of the quality of Rewritable Hybrid Media and its component pa
22、rts. Such standards can be referred to when developing equipment and application standards, or determining the quality of the data carriers. Such test specifications form the basis for development of measuring equipment for process control and quality assurance purposes during the rewriting process
23、as well as afterwards. This International Standard provides requirements and guidelines to achieve a specified quality requirement for applications making use of Rewritable Hybrid Media. These requirements also address the fact that any batch of Rewritable Hybrid Media is heterogeneous, with some it
24、ems that are relatively new being intermixed with other items that have been erased and re-written many times. Procedures outlined in this International Standard ensure, irrespective of the age and number of cycles achieved by an item of Rewritable Hybrid Media, that the minimum required quality out
25、put is maintained. The bar code symbol needs to be produced in such a way as to be reliably decoded at the point of use, if it is to fulfil its basic objective as a machine-readable data carrier. Similarly, the RFID tag needs to be encoded in a correct manner to be reliably read at the point of use.
26、 This International Standard specifies the overall quality process and associated methodology for Rewritable Hybrid Media. This International Standard determines quality characteristics to ensure that various types of product combination and integrated Rewritable Hybrid Media system can be implement
27、ed in a reliable and robust manner. This International Standard contributes to the interoperability of data carriers and devices that support this technology. In addition, as the Rewritable Media technology develops, this International Standard will provide a benchmark to assess whether the new deve
28、lopments are capable of being applied in a manner compatible with existing data carriers.

29、data carriers 1 Scope This International Standard specifies methodologies to be used for the conformance of rewritable hybrid media data carriers, which combine RFID tag technology with linear and/or two-dimensional bar code symbologies that are written to an erasable substrate. Three main product c
30、onfiguration types are addressed within this International Standard: Rewritable Media, which supports the rewriting of linear or two-dimensional symbols; Rewritable Hybrid Media, which integrates the Rewritable Media with an RFID tag; Rewritable Media combined with RFID technology that are physicall
31、y separate data carriers but still require their data encoding processes to be integrated as part of a Rewritable Hybrid Media system. In particular, this International Standard defines the base requirements for Rewritable Media and Rewritable Media devices (see 6.2), defines additional methods for
32、process control of the Rewritable Media over multiple erasure and rewrite cycles (see 6.4), defines reference standards for evaluating the RFID tag component (see 7.2 and 7.3), defines additional methods for process control of the RFID component over multiple erasure and rewrite cycles (see 7.4), pr
33、ovides information to ensure that the data encoded in the bar code symbology and RFID data carrier are synchronous, i.e. are derived from the same source data set (see Clause 8). NOTE Depending on the application, the encoded data can be identical or different (e.g. one data carrier could provide ad
34、ditional data). Because of the interdependency between the Rewritable Hybrid Media and the rewrite device used to create the optical image, the entire Rewritable Hybrid Media system needs to be taken into account to define conformance. Therefore, there is a requirement to define the capability of ac
35、hieving a given print quality grade as defined in relevant standards. This Rewritable Hybrid Media system approach has the additional advantage of not being prescriptive on the types of media and “print“ technologies that may be used now or developed in future. As long as a print technology/media co
36、mbination meets the print quality grades, it can be considered conformant with this International Standard.

44、bles repeated writing and erasing of optical data including bar code symbologies and eye readable data. This is achieved by incorporating an optical imaging layer in the media substrate. The process of erasing and then rewriting is normally achieved in a device that combines the functions, or in sep
45、arate devices addressing each process. Other than the system meeting the basic conformance requirements specified in Clause 6, this International Standard places no constraints on the type of media substrate nor the “printing“ process. Example technologies are described in Annex A. The Rewritable Hy
46、brid Media allows applications to exploit the benefits of optical and radio frequency technologies in innovative ways. A key advantage is that the media device can be reused for multiple cycles. 6 Conformance tests for the Rewritable Media system 6.1 General This clause applies equally to Rewritable
47、 Media when used alone or as a component of Rewritable Hybrid Media. A Rewritable Media system shall consist of Rewritable Media products and a device capable of erasing the media and rewriting this with a new set of barcode(s) and eye readable data. The following sub-clause specifies procedures for
48、 making conformance claims for the Rewritable Media product and capabilities of the Rewritable Media device. Additional sub-clauses define factors that need to be taken into account for process control purposes; and finally a range of process control methods are defined, increasing in sophistication
