Overview
ISO 20302:2022 - Health informatics - Health cards - Numbering system and registration procedure for issuer identifiers defines a standardized approach to uniquely identify healthcare application providers and health‑card holders on machine‑readable ID‑1 cards used across national borders. The document targets health cards where the card issuer and the healthcare application provider are the same party and is technology‑neutral, aligning with existing physical and recording standards. Primary goals are improved patient safety, cross‑border interoperability, and reliable exchange of healthcare data via health cards.
Key topics and technical requirements
- Numbering system for issuer identifiers
- IIN (Issuer Identification Number) structure: begins with the sector code “80” for healthcare, followed by a three‑digit ISO 3166‑1 country code, then an issuer identifier (variable length up to 13 digits) and a check digit.
- Formatting of digits after “80[xxx]” is determined by regional healthcare authorities.
- RID (Registered application provider identifier)
- RID is used as part of an AID for IC (integrated circuit) cards; the structure follows ISO/IEC 7816‑4 and detailed RID fields are given in Annex A.
- RID uses a 5‑byte field with registration categories encoded in the first nibble: ‘A’ for international, ‘D’ for national, ‘E’ for standard identification. Category ‘E’ references an OID (object identifier).
- Registration procedure
- Registration and management of RIDs follow the process in ISO/IEC 7816‑5.
- Scope limits and security
- Applies to ID‑1 machine‑readable healthcare cards used across two or more countries/areas. Security considerations are left to each card system’s requirements; physical and recording characteristics reference relevant ISO/IEC standards.
- Technology independence
- The numbering and registration approach is designed to be independent of specific card technologies and recording techniques.
Applications and who uses it
ISO 20302:2022 is intended for:
- Card issuers (hospitals, health funding agencies) issuing machine‑readable health cards.
- Healthcare application providers and systems integrators implementing card‑based workflows (appointments, access control, funding).
- National and regional healthcare authorities defining issuer formatting rules and registration processes.
- Smart‑card manufacturers, middleware vendors and IT teams ensuring interoperability in cross‑border healthcare services.
Practical benefits include unambiguous issuer IDs for secure data exchange, improved cross‑border patient care continuity, and standardized registration that supports global interoperability.
