Your comments on this draft are welcome and will assist in the preparation of the consequent standard. If no comments are received to the contrary, then the UK will approve this draft. There is a high probability that this text could be adopted by CENELEC as a reference document for harmonization or as a European Standard. Recipients of this draft are requested to comment on the text bearing in mind this possibility. UK Vote Please indicate whether you consider the UK should submit a negative (with reasons) or positive vote on this draft. BSI Committee Responsibilities Whether or not the standard is published in its original (international) form, or as a formal British Standard Implementation, the BSI committee's responsibilities are to: - aid enquirers to understand the text; - present to the responsible international committee any enquiries on interpretation, or proposals for change, and keep UK interests informed; - monitor related International and European developments and promulgate them in the UK. Submission The guidance given below is intended to ensure that all comments receive efficient and appropriate attention by the responsible BSI committee. Annotated drafts are not acceptable and will be rejected. All comments must be submitted, preferably electronically, to the Responsible Committee Secretary at the address given on the front cover. Comments should be compatible with Version 6.0 or Version 97 of Microsoft® Word for Windows, if possible; otherwise comments in ASCII text format are acceptable.

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. 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 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 possibility 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. ISO/IEC 11694-4 was prepared by Joint Technical Committee ISO/IEC JTC 1, , Subcommittee SC 17, Identification cards and related devices. This third edition cancels and replaces the second edition which has been technically revised. ISO/IEC 11694 consists of the following parts, under the general title Identification cards Optical memory cards Linear recording method: Part 1: Physical characteristics Part 2: Dimensions and location of the accessible optical area Part 3: Optical properties and characteristics Part 4: Logical data structures Part 5: Data format for information interchange for applications using ISO/IEC 11694-4 Annex B Part 6: Use of biometrics on an optical memory card Licensed Copy: London South Bank University, London South Bank University, Sat Mar 17 03:48:45 GMT+00:00 2007, Uncontrolled Copy, (c) BSI ISO/IEC FCD 11694-4 vi © ISO/IEC 2007 All rights reserved Introduction This part of ISO/IEC 11694 is one of a series of standards describing the parameters for optical memory cards and the use of such cards for the storage and interchange of digital data. The standards recognize the existence of different methods for recording and reading information on optical memory cards, the characteristics of which are specific to the recording method employed. In general, these different recording methods will not be compatible with each other. Therefore, the standards are structured to accommodate the inclusion of existing and future recording methods in a consistent manner. This part of ISO/IEC 11694 is specific to optical memory cards using the linear recording method. Characteristics which apply to other specific recording methods shall be found in separate standards documents. This part of ISO/IEC 11694 defines the logical data structures and the extent of compliance with, addition to, and/or deviation from the relevant base document ISO/IEC 11693.
