Overview
ISO/IEC 23917:2023 - "Telecommunications and information exchange between systems - Near Field Communication Interface and Protocol 1 (NFCIP-1) - Protocol test methods" - defines standardized protocol test methods for NFCIP‑1 as specified in ISO/IEC 18092. This second edition aligns protocol tests with the latest NFCIP‑1 base standard and clarifies test procedures and scenarios. RF radio‑frequency test methods for NFCIP‑1 are addressed separately in ISO/IEC 22536.
Key topics and requirements
- Scope and conformance: Defines what constitutes protocol conformance testing for NFCIP‑1 and references normative documents required for test implementation.
- Test apparatus and setup: Specifies equipment concepts for both Target-test-apparatus and Initiator-test-apparatus, methods to generate I/O character timing, and procedures for measuring and monitoring RF I/O protocol behavior.
- Activation modes: Test methods cover both passive and active communication modes, including Activation at different subcarrier rates (e.g., f/128, f/64, f/32) and associated Single Device Detection (SDD) procedures.
- Transport protocol tests: Procedures for verifying transport protocol behavior during activation, data exchange and deactivation between Initiator and Target.
- Protocol operations and PDUs: Detailed test sequences for handling ATR_REQ/RES, PSL_REQ/RES, DEP_REQ/RES (information and supervisory PDUs including chaining and timeout bit behavior), DSL/RLS and WUP exchanges.
- Timing, frame format and RFU bits: Tests include timing measurements, frame format verification and treatment of reserved/ RFU bits in protocol frames.
- Test scenarios and reporting: Contains scenario descriptions, test command lists and normative test report templates (Annex A for Target tests and Annex B for Initiator tests).
Applications and who uses it
- NFC device manufacturers - to validate protocol conformance of NFC initiators and targets.
- Test laboratories and certification bodies - to run reproducible protocol tests and produce standardized test reports.
- Chipset, module and reader developers - to ensure interoperability with NFCIP‑1 peers and diagnose protocol-level issues.
- System integrators and QA teams - to build conformance test suites and meet product certification requirements.
Practical uses include interoperability verification, compliance testing during product development, and formal certification preparation.
