IEC 62908-22-10:2024

Overview

IEC 62908-22-10:2024 is an international standard developed by the International Electrotechnical Commission (IEC) that specifies standardized measuring conditions and methods for evaluating the performance of fingerprint recognition systems utilizing under-display optical imaging fingerprint sensing technology. This standard is essential for manufacturers and testing facilities involved in the development and assessment of touch and interactive displays that use the display panel itself as the illumination source for fingerprint recognition.

By providing a unified approach to measuring key metrics such as system resolution, signal-to-noise ratio (SNR), false acceptance rate (FAR), and false rejection rate (FRR), IEC 62908-22-10:2024 supports improved product consistency, enhanced user security, and better interoperability across hardware platforms.

Key Topics

• Standard Measuring Environmental Conditions
  • Specifies temperature, humidity, and air pressure requirements for consistent testing.
