ISO/IEC 14443-2:2016
Identification cards — Contactless integrated circuit cards — Proximity cards — Part 2: Radio frequency power and signal interface
ISO/IEC 14443-2:2016 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).
It does not specify the means of generating coupling fields, nor the means of compliance with electromagnetic radiation and human exposure regulations, which can vary according to country.
