Thanks for that clarification! I honestly never considered that technical aspect of the scans, as I do not have Global Entry, and I didn't know that retina scans are technically infeasible to utilize for ID purposes. You've given me something further to research: are iris scans harder to defeat with false information (like specialized contacts) than fingerprint scans (with whatever the hell they can be falsified with). There goes my morning! :)
