Описание (английский):

This document specifies the characteristics of the fields to be provided for power and bi-directional communication between proximity coupling devices (PCDs) and proximity cards or objects (PICCs). This document does not specify the means of generating coupling fields, nor the means of compliance with electromagnetic radiation and human exposure regulations, which can vary depending on the country.

Overview

ISO/IEC 14443-2:2020 - Radio frequency power and signal interface - is part of the ISO/IEC 14443 series for contactless proximity objects (proximity cards and security devices). This fourth-edition standard defines the electrical and radio-frequency characteristics required to provide power and bi‑directional communication between a proximity coupling device (PCD) (reader) and a proximity card or object (PICC). It covers field characteristics, modulation and coding methods, and limits for electromagnetic disturbance, but does not prescribe how coupling fields are generated or national electromagnetic exposure compliance procedures.

Key Topics

Power transfer: characteristics of the operating field used to power passive proximity cards (operating volume, field strength and frequency ranges).

Signal interface: general requirements for bi‑directional communication between PCD and PICC.

Communication Type A and Type B: electrical signalling, bit rates, modulation schemes and coding:

PCD→PICC: modulation formats, bit representation and timing.
PICC→PCD: load modulation, subcarrier use, modulation indices and reception constraints.

Modulation & coding terms: references to ASK, BPSK, NRZ‑L, Manchester and modified Miller coding methods (terms and definitions clarified).

Timing & synchronization: guard times (TR0/TR1), bit durations and pulse timing constraints to ensure reliable exchange.

Electromagnetic disturbance levels: limits for parasitic emissions and defined limits for PCDs and PICCs to minimize interference.

Compliance & testability: references normative test methods and the use of Reference and Active Reference PICCs to define operating volumes and compliance verification.

Applications

ISO/IEC 14443-2:2020 is directly applicable to the design, manufacture and certification of:

Contactless smart cards and tags (proximity cards).

Card readers / POS terminals and other proximity coupling devices.

Secure ID documents (access control badges, e‑ID, e‑passports when applicable).

Systems employing short‑range contactless communication where harmonized RF power and signal interfaces are required.

Adoption ensures interoperability between PICCs and PCDs from different vendors and supports reliable implementations of contactless payment, access control and identity systems.
