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. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. 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 part of ISO/IEC 15693 may be the subject of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights. International Standard ISO/IEC 15693-2 was prepared by Joint Technical Committee ISO/IEC JTC 1,Information technology, Subcommittee SC 17,Identification cards and related devices. ISO/IEC 15693 consists of the following parts, under the general titleIdentification cards Contactless integrated circuit(s) cards Vicinity cards: ?Part 1: Physical characteristics ?Part 2: Air interface and initialization ?Part 3: Anticollision and transmission protocol ?Part 4: Extended command set and security features Annex A of this part of ISO/IEC 15693 is for information only. BS ISO/IEC 156932:2000 Licensed Copy: sheffieldun sheffieldun, na, Tue Nov 21 05:52:46 GMT+00:00 2006, Uncontrolled Copy, (c) BSI IS/OIEC -396512:(0002)E ?v Introduction ISO/IEC 15693 is one of a series of International Standards describing the parameters for identification cards as defined in ISO/IEC 7810 and the use of such cards for international interchange. This part of ISO/IEC 15693 describes the electrical characteristics of the contactless interface between a vicinity card and a vicinity coupling device. The interface includes power and bi-directional communications. This part of ISO/IEC 15693 does not preclude the incorporation of other standard technologies on the card. Contactless card standards cover a variety of types as embodied in ISO/IEC 10536 (Close-coupled cards), ISO/IEC 14443 (Proximity cards), ISO/IEC 15693 (Vicinity cards). These are intended for operation when very near, nearby and at a longer distance from associated coupling devices respectively. The International Organization for Standardization (ISO) and International Electrotechnical Commission (IEC) draw attention to the fact that it is claimed that compliance with this part of ISO/IEC 15693 may involve the use of patents. ISO and IEC take no position concerning the evidence, validity and scope of these patent rights. The holders of these patent rights have assured ISO and IEC that they are willing to negotiate licences under reasonable and non-discriminatory terms and conditions with applicants throughout the world. In this respect, the statements of the holders of patent rights are registered with the ISO and IEC.

The RF operating field that supplies power to the VICC from the VCD is modulated for communication from the VCD to the VICC, as described in clause 7. 6.1? Frequency The frequencyfcof the RF operating field is 13,56 MHz ±7 kHz.Operating field 6.2? Operating field A VICC shall operate as intended continuously betweenHminandHmax. The minimum operating field isHminand has a value of 150 mA/m rms. The maximum operating field isHmaxand has a value of 5 A/m rms. A VCD shall generate a field of at leastHminand not exceedingHmaxat manufacturers specified positions (operating volume). In addition, the VCD shall be capable of powering any single reference VICC (defined in the test methods) at manufacturers specified positions (within the operating volume). The VCD shall not generate a field higher than the value specified in ISO/IEC 15693-1 (alternating magnetic field) in any possible VICC position. Test methods for determining the VCD operating field are defined in ISO/IEC 10373-7. 7?Communications signal interface VCD to VICC For some parameters several modes have been defined in order to meet different international radio regulations and different application requirements. From the modes specified any data coding can be combined with any modulation. 7.1? Modulation Communications between the VCD and the VICC takes place using the modulation principle of ASK. Two modulation indexes are used, 10% and 100%. The VICC shall decode both. The VCD determines which index is used. Depending on the choice made by the VCD, a “pause“ will be created as described in Figure 1 and Figure 2.
