For a long-term client of mine, I have been issued a laptop because of the company’s stringent security efforts. To log onto the laptop I must not only enter my username and password but also pass a fingerprint test.
It works wonderfully and amazes me. I swipe my index finger down a small reader that scans my fingerprint and approves me. Someday, retinal images!
