foreword

This document is in accordance with the provisions of GB/T 1:1-2020 "Guidelines for Standardization Work Part 1: Structure and Drafting Rules for Standardization Documents"

drafting:

This document is part 2 of GB/T 42756 "Card and Identification Security Equipment Contactless Proximity Object": GB/T 42756

The following parts have been published:

--- Part 1: Physical characteristics;

--- Part 2: RF power and signal interface;

--- Part 3: Initialization and anti-collision;

--- Part 4: Transmission protocol:

This document is modified to adopt ISO /IEC 14443-2:2020 "Card and Identification Security Equipment Contactless Proximity Object Part 2

Sub: RF Power and Signal Interface":

The technical differences between this document and ISO /IEC 14443-2:2020 and their reasons are as follows:

--- ISO /IEC 14443-1:2018 is replaced by GB/T 42756:1-2023 with normative references, the consistency between the two documents

The degree of stability is modified to adapt to the technical conditions of our country (see 6:2, 8:2:2:2):

--- Replaced ISO /IEC 14443-3:2018 with the normative reference document GB/T 42756:3-2023, one between the two documents

The degree of consistency is equivalent (see Chapter 2):

The following editorial changes have been made to this document:

---Incorporated the content of ISO /IEC 14443-2:2020/Amd1:2021, the outer margins of the terms involved are in vertical

Double lines (||) are marked (see Chapter 4, 6:3, Table 22, 9:1:2, 10:2);

---Incorporated the content of the corrigendum of ISO /IEC 14443-2:2020/Cor1:2021, the outer margins of the terms involved are marked with vertical

Straight double lines (||) are marked (see 8:1:3:3, 8:1:3:4, 9:1:3:2, 9:1:3:3);

---Added the normative reference document ISO /IEC 14443-4, because it is quoted in ISO /IEC 14443-2:2020/Amd1:2021

ISO /IEC 14443-4 (see 6:3):

---In ISO /IEC 14443-2:2020/Cor1:2021, Figure 29~Figure 30 in the original text is changed to Figure 11~Figure 12, so the original Figure 11~

Figure 28 corresponds to Figure 13 to Figure 30 of this document, and the corresponding references are revised at the same time (see Figure 11 to Figure 30, ISO /IEC 14443-4:

Figure 11~Figure 30 of:2018);

---In ISO /IEC 14443-2:2020/Cor1:2021, the title of 9:1:3:2 of the original text is changed to "bit rate 3fc/4 and 3fc/2

Bit representation and coding of ", add 9:1:3:3 "Bit representation and coding of bit rate fc and 2fc":

Introduction

Contactless card standards include ISO /IEC 10536 (tightly coupled card), GB/T 42756 (proximity card) and GB/T 22351 (proximity card)

card) and other types: These types of equipment are designed to operate at very close, close and long distances respectively from the associated coupling device:

GB/T 42756 "Card and Identity Recognition Security Equipment Contactless Proximity Object" stipulates that identification cards and identification cards in accordance with GB/T 14916

Comply with the technical requirements for flexible thin cards in GB/T 28177:1, and use these cards for information exchange: This technology provides standard card

Forms other than formats provide the possibility to approach type objects: In addition, it does not exclude the use of other technologies on the card, such as GB/T 42756:1 attached

Techniques in Record A:

GB/T 42756 consists of four parts:

--- Part 1: Physical properties: The purpose is to specify the physical characteristics of proximity objects:

--- Part 2: RF power and signal interface: The purpose is to specify the Proximity Coupling Device (PCD) and the Proximity Card or Object

(PICC) provides the characteristics of the field of energy and two-way communication:

--- Part 3: Initialization and anti-collision: The purpose is to specify requirements for contactless proximity object initialization and anti-collision:

--- Part 4: Transmission protocol: The purpose is to establish a half-duplex block transfer protocol required for a contactless environment and to specify activation and deactivation

A step of:

Part 2: RF power and signal interface

1 Scope

This document specifies the field for providing energy and two-way communication between a proximity coupling device (PCD) and a proximity card or object (PICC):

characteristics: This document does not specify methods for generating coupling fields, nor does it specify methods for complying with regulations on electromagnetic radiation and human exposure:

This document is applicable to the design, production, application and testing of proximity cards and equipment:
