No retina scan for PreCheck, that's for Global Entry / Nexus.
- jessriedel 11y agoYea, thanks. I was being sloppy and using "a precheck program" to refer collectively to Global Entry, Nexus, and PreCheck. Obviously, the argument still applies to PreCheck with regard to fingerprints.
- grkvlt 11y agoNo retina scan for anything, actually. NEXUS uses iris scanners [1] for biometric identification. In fact, pretty much anything that is reported as using a 'retina' scan is probably not, and is also an iris scan. Retinas are pretty useless as a biometric, and are quite hard to scan without opthamological equipment. Irises have the dual benefits of being unique to the individual, and visible on the outside of an individual.

- spdustin 11y agoThanks 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! :)
- sokoloff 11y agoIris scans are optional for Nexus as well. It's only require if you want to use the Nexus stations to enter Canada by commercial air. I have a Nexus card (just got it last month) and if I only use it to enter Canada by land, sea, or private aircraft, I can skip the iris scan.
- ibejoeb 11y agoOnly NEXUS requires an iris scan, and only for entering Canada via an air border.
