$3,000? What is an iris scanner other than a high-resolution camera? You can buy a dozen megapixel camera for under $100 if the iPhone's camera isn't good enough. Does the other $2,900 pay for the database usage, or is there a separate subscription charge for that too? Even if it includes a fingerprint scanner, those are pretty cheap now.
Some cops appear to be spending "free" federal money for toys instead of law enforcement.
Yeah old boys network.
Iris scanners have been around for the last 25 years. They are used for identification for bank employees in some cases.
