Exactly. I won't let anyone but a doctor scan my retina. I have it done once a year, and I don't see this being mainstream anytime soon. Way too expensive to be done properly.
Fortunately, this is an iris scanner instead. Much less expensive and not invasive.
Electronics magazines are saying that factories are gearing up to produce zillions of dedicated iris camera modules, and in a couple of years, almost every phone might have one.
Not interested in an iris scanner either. I'm just plain and simply AFRAID of anything going near my eyes, Forget about the thought of infrared, or whatever they will use, bombarding my eyes. Paranoid? Yes. Embarrassed about it? No.
I think you should be very embarrassed to be afraid
before you find out how something works. Wait until you find out,
THEN you can be afraid it it's warranted
Does it take a picture of your iris, or does it use any type of invisible light (infrared etc.) to scan the iris?
See, now asking questions is the right spirit.
It illuminates your face with IR light. This has the following benefits: it allows the camera to see features in darkly colored eyes; it doesn't blind you like a visible light would; it works in the dark.
While there are iris scanning apps that use the regular front-facing camera, Samsung (and others) use a dedicated camera which is tuned to the subtle IR illumination it uses.
We're bombarded all our lives with IR light, from the sun, to photograph flashes, to remote control reflections, to smartphone sensors to see if we're holding a phone to our face.
Heck, over half of the energy that arrives from the sun, is in the IR range. So if IR illumination of our face is a problem, we've been in trouble for eons.
