The technology has never failed, not once, only when I have had wax on my finger or water has it not scanned so kind of a non issue.
TouchID never works for me when fingertips are wet or even slightly damp - rest of the time it works fine for me.
Our Neighbour is 85 yo - very tech savvy inventor - he has never got touch ID to work for him, he would love an iris scanner.

Why do people ALWAYS immediately assume that adding feature X means the removal of feature Y? Did Apple get rid of passwords when they added fingerprints?
I wonder about that too.
Perhaps because people are ALWAYS afraid of losing what they have been used to, even though they simultaneously love to complain about "missing innovation"? Must be some thing in our nature ;-)

Does Apple realize that HP and Microsoft has Iris scanning already, I have an HP laptop that has Iris scanning and it works extremely well.
No, I expect this is news to them, as they hardly do any research. Apple will be grateful to you for bringing it to their attention, thus avoiding potential embarrassment had they announced the feature as their own innovation.
I have a Windows phone that has Iris scanning also and it works extremely well a also.
Good to know, I have never used it, I am sure it will prove to be useful in one way or another.
