Based on the ISO/IEC definition, FMR is the proportion of trials measured during a performance test, while FAR is the proportion of "units of work" performed by a biometric system. This comment gives the option for both. Subtle, but definitely worth the suggestion.

Comment
Biometric performance testing should be done following best practices or internatioal standards to measure the false acceptance or rejection objectively. Such standards should also be refered correctly.
ISO/IEC TS 19795-9 "Information technology — Biometric performance testing and reporting — Part 9: Testing on mobile devices" uses FAR, instead of FMR, for the performance testing for mobile biometrics.
ISO/IEC 19795-1 "ISO/IEC 19795-1 "Information technology — Biometric performance testing and reporting — Part 1: Principles and framework" states that confidence level shall also be determined to estimate the FAR/FMR to show that how the estimated FAR/FMR may be accurate.
[ISO/IEC30107-1] is a standard for the PAD testing and explains that zero-effort impostor attempt is an example of human PAI. [ISO/IEC30107-1] doesn't mention or explain the FMR at all.
The Biometrics Security iTC has created a guidance for biometric performance testing refering ISO/IEC 19795-1, however, this guidance doesn't require full compliance with ISO/IEC 19795-1 to enable cost-effective performance testing.
Suggested Change
The biometric system SHALL operate with a false accept rate (FAR) or false-match rate (FMR) [ISO/IEC2382-37] of 1 in 10000 or better with adequate confidence level. Testing of biometric performance SHALL be in accordance [ISO/IEC19795-1].
