Retina “scans” have a range of a few inches at best.The DMV clerk didn’t know what they were talking about.
Now don’t go round being the voice of sanity on the deranged threads, you’ll get a reputation.
You may be correct. But how about an iris scan?

“In contrast to the retinal scanners, iris scanners are of two main types: active and passive. The active system works from 3 to 14 inches and also requires the user to move forward and backwards so the camera is adjusted properly. In contrast the passive system can work over longer distances one to three feet. The main technology developer is Iridian Technologies, which holds the patents to the concepts and technologies involved.”
I must admit the distance from the camera was over 14”, more like 4-5 feet.
I appreciate you input, you seem confident in your answer concerning retina scans. The photo feature contrast on the picture they printed seemed hard. Wonder what they were doing?
