* Question
What is the title and scope of the ISO/IEC 14443 international standard?
* Answer
The ISO/IEC 14443 international standard is titled:
“Identification cards — Contactless integrated circuit cards — Proximity cards.”
Overview and Scope
The standard defines the communication protocols, electrical characteristics, and data exchange methods for proximity contactless smart cards (commonly known as RFID cards or NFC proximity cards).
It specifies how a proximity coupling device (PCD), such as a reader, communicates with a proximity integrated circuit card (PICC) over short distances (typically up to 10 cm).
Structure of ISO/IEC 14443
The standard is divided into four parts, each describing a specific layer of communication:
Part 1: Physical characteristics
Part 2: Radio frequency power and signal interface
Part 3: Initialization and anticollision
Part 4: Transmission protocol
Common Applications
Contactless payment cards (e.g., credit/debit cards using NFC).
Electronic passports (e-passports).
Access control systems and transport ticketing.
Summary
The ISO/IEC 14443 standard — “Identification cards — Contactless integrated circuit cards — Proximity cards” — defines how contactless smart cards communicate via radio frequency within short ranges, forming the foundation for technologies like NFC, RFID, and e-passports.
