The BMT-20 is a binoculars-type, simultaneous dual iris capture system intended for enrollment applications, especially very large scale programs, in which subjects are presumed to have no prior experience in providing iris biometrics samples. Developed for and proven in the highly demanding India UID program, the BMT-20 offers the fastest capture speeds, superior usability, minimal failure-to-captures rates and outstanding image quality.
