ISO/IEC 15693-3:2026 defines how contactless cards—often called vicinity cards—communicate reliably and securely in environments where many such cards may be present. Commonly used for access control, transportation tickets, library cards, and corporate IDs, the protocol ensures that devices can quickly and accurately single out and interact with one card among many, even over a larger communication range than traditional proximity cards.

Scope and Requirements

• Details protocols and commands for initial communication between a vicinity integrated circuit card (VICC) and a vicinity coupling device (VCD)
• Defines procedures for anticollision, allowing systems to identify and communicate with one card among several
• Introduces optional efficiencies for the rapid selection of specific cards
• Provides security enhancements for card communication, including command-based authentication and data protection
• Compatible with complementary standards such as ISO/IEC 7816-6, supporting extended functionality (e.g., additional data formats, cryptographic modules)

Key Implementation Factors

Organizations deploying large-scale contactless systems (in transit, logistics, workplace security, or education) use ISO/IEC 15693-3:2026 to:

• Guarantee interoperability between cards/devices from multiple manufacturers
• Avoid communication errors and ensure fast response even in crowded card environments
• Establish secure, authenticated sessions for protecting personal data

Key highlights:

• Robust anticollision algorithm prevents cross-talk and missed reads in high-density card environments
• Comprehensive security framework, including command authentication and data integrity
• Enhances scalability—supports large-scale deployments with many cards in the field

ISO/IEC TS 23220-2:2026 addresses the underpinnings of modern digital ID apps (electronic ID, or eID) used on mobile devices. This standard is vital for government-issued mobile IDs, driver’s licenses, digital health cards, organizational badges, and any app-based identification solution. Increasingly, secure digital credentials are replacing physical cards, requiring consistent ways to structure, encode, and exchange identity data between apps and verifiers.

Scope and Requirements

• Specifies standardized data objects and encoding rules for generic eID systems—crucial for mobile document (mdoc) infrastructure
• Outlines data models for personal attributes, issuing authority, and document authenticity
• Supports data exchange between mdoc apps and verification applications, whether local or remote
• Aligns with globally accepted encoding standards (CBOR, JSON), ensuring both compactness and interoperability
• Reference to established protocols and encoding schemes (ISO 3166, biometric image formats, RFC 8949 for CBOR)

Key Implementation Factors

Entities building, maintaining, or operating mobile eID systems use ISO/IEC TS 23220-2:2026 to:

• Enable seamless, secure, and interoperable digital identity transactions across national and sectoral boundaries
• Ensure correct encoding/decoding of identity data (e.g., names, birth dates, biometric images) between devices and backend systems
• Lay the groundwork for secure, privacy-centric eID system design—foundational for identity assurance and trust management

Key highlights:

• Flexible data modeling for diverse ID use cases (person attributes, credentials, issuer metadata)
• Support for multiple transmission formats: binary (CBOR) and text-based (JSON)
• International compatibility for biometric, legal, and administrative data

ISO/IEC TS 23220-3:2026 – Protocols and Services for Installation and Issuing of Mobile eID

Cards and Security Devices for Personal Identification — Building Blocks for Identity Management via Mobile Devices — Part 3: Protocols and Services for Installation and Issuing Phase

ISO/IEC TS 23220-3:2026 builds on Part 2 by detailing how eID software (mdoc apps) is installed, how identity attributes are issued to them, and how credentials are managed securely. This is essential for government, enterprise, and financial issuers seeking to scale digital identity to millions of devices while maintaining the highest standards of security and privacy.

Scope and Requirements

• Normalizes protocols, interfaces, and services for installation (onboarding) and the issuing phase in mobile eID-System infrastructures
• Specifies discoverability and attestation mechanisms, so that only trusted devices and apps participate
• Outlines security and privacy protections, including end-to-end encryption and privacy-enhancing techniques
• Defines session management, device attestation, and provisioning flows for mobile credentials
