Comment In Soviet Russia LCD screens YOU (Score 1, Interesting) 69
If you were to put these touchscreens as the primary UI on vending machines, ticket machines, ATMs and the like, you could harvest hundreds of thousands of fingerprints without anybody realizing it. I bet that we'll see more and more companies trying to con people into "use your fingerprint to make calls, pay for your shopping, access your ATM" type of deals. I also bet that these screens will wind up in cellphones as a "standard" feature. You'll be told that you can switch scanning off and use it only as a touchscreen if you like, but who knows whether the scanning function is on or off and whether the phone is sending your biometric data places without your consent or not.
This tech is a definite threat to privacy.
