Foreword

GB/T 22351 in the "Identification cards - Contactless integrated circuit cards Proximity card" always be entitled divided into the following four parts.

--- Part 1. Physical characteristics

--- Part 2. Air Interface and Initialization

--- Part 3. Anti-collision and transmission protocol

--- Part 4. Extended command set and security features this section GB/T 22351 Part 2.

This section identical with 15693-2 international standard ISO/IEC .2000 "Part 2 Identification cards - Contactless integrated circuit cards Proximity cards Score. Air Interface and Initialization "(in English).

For ease of use, the ISO/IEC 15693-2:2000 This part made the following editorial changes.

a) instead of as a decimal by decimal comma ",". ",";

b) Remove the preface to international standards by modifying the ISO/IEC 15693-2:2000 Introduction.

Appendix A of this section is informative appendix.

This part is proposed by the Ministry of Industry and Information Technology of the People's Republic of China.

This part of the National Information Technology Standardization Technical Committee (SAC/TC28) centralized.

Introduction

GB/T 22351 series of standards is one of the identification cards used are described GB/T 14916-defined parameters and identification card of international exchange.

This section GB/T 22351 describes Proximity card air interfaces and initialization.

This section GB/T 22351 standard does not exclude other technical cards, such as A standard referenced in the data appendix.

Non-contact IC card standard covers ISO/IEC 14443 (proximity cards) and GB/T 22351 (proximity cards) included in each Types of cards. They are associated with work in the case of close coupling devices and more distant.

This part of the release mechanism to draw attention to the fact that, when you declare compliance with this section, related patents may be used in this section involved.

This part of the release mechanism for the patent scope, validity and verification of data is not made any comments.

The patent holder has to ensure that international standards of the issuing authority, he is willing to reasonable and non-discriminatory terms and conditions with any applicant, Authorization for Use on license negotiations. In this regard, the patent holder has filed a statement published in the international standards bodies. Relevant information Material can be obtained from the following address.

Identification cards - Contactless integrated circuit cards Proximity cards Part 2. Air Interface and Initialization

1 Scope

This section GB/T 22351 specifies the coupling between adjacent devices (VCD) and proximity cards (VICC) provides power and two-way the nature and characteristics of the field of communication.

This part should the rest of GB/T 22351 combine them to use.

This section does not specify the means to produce coupling field, nor the means in line with the provisions of human exposure to electromagnetic radiation, and the rules and regulations, the regulations may in accordance with national regulations and standards change.
