Every biometric technology meets with certain challenges. When reviewing test results, it is essential to consider the environment and protocols of the test. Much industry testing is performed in laboratory settings on images acquired in ideal conditions. Performance in a real world application may result in very different performance, as there is a learning curve for a would-be user of the system, and not every candidate will enroll properly or quickly the first time. There are some issues which affect the functionality and applicability of iris recognition technology in particular.
