* Low occurrence of false positives
* Extremely low (almost 0%) false negative rates
* Highly reliable because no two people have the same retinal pattern
* Speedy results: Identity of the subject is verified very quickly

* Measurement accuracy can be affected by a disease such as [[cataracts]]
* Measurement accuracy can also be affected by severe [[astigmatism]]
* Scanning procedure is perceived by some as invasive
