This part of ISO/IEC 10536 specifies the nature and characteristics of the fields to be provided for power and bi-directional communications between card coupling devices (CCDs) and contactless integrated circuit(s) cards (CICCs) of the ID-1 card type in slot or surface operation. This part of ISO/IEC 10536 does not specify the means of generating coupling fields, nor the means of compliance with electromagnetic radiation regulations. This part of ISO/IEC 10536 is to be used in conjunction with ISO/IEC 10536-1 and ISO/IEC 10536-2. NOTE 1 Other types of contactless integrated circuit(s) cards, formats or interfaces, which operate at various distances, may be developed in the future, which may call for additions to be made to this part of ISO/IEC 10536 or may require other International Standards to be written.
