Validation of Contactless Interfaces

CL Verify A is the core device of COMPRION's modular solution designed especially for the development of the contactless interface of NFC-enabled (mobile) devices as well as for contactless smart cards and tags. It offers a robust set of features, encompassing contactless communication simulation, monitoring (sniffing), and capturing functionalities. CL Verify A provides extensive support for industry standards including NFC Forum, EMVCo, ISO/IEC 14443, ISO/IEC 18092, and ISO/IEC 15693. Equipped with a digital storage oscilloscope and vector field measurement capabilities, it empowers users with precise signal analysis and evaluation of magnetic fields. 

CL Verify A provides comprehensive testing and evaluation of various NFC-equipped products, such as car door handles, contactless readers, contactless cards, wearables, and more, to ensure their market readiness.

Use Cases Include:

  • Execution of conformance test cases, aligning with NFC Forum, GSMA TS.27 NFC Handset Test Book, and EMVCo standards.
  • Development and debugging of NFC-enabled devices including contactless cards, tags, terminals/readers, frontends (CLFs), and IoT modules with NFC interface.
  • Analysis of NFC fields, optimization of NFC antenna integration.
  • Interoperability testing of contactless interfaces.
  • Quality assurance measures.
