Techie here. Actually, hardware designer, so I'm about 10 levels above a 'techie'.
The iPhone apps you're talking about are jokes. Not in the sense that they're bad, but literally they're a joke. Like me having a "24" ringtone
on my phone.
Touch screens do not have anywhere near the resolution needed to read a fingerprint. Why would they? It's not needed to execute the function of the
phone. On top of which, fingerprint reading tech that I've designed with is qualitatively different from touch screen technology. A lot of it is
straight video capture with a little CCD, some of them use capacitive swipe sensing, and a very few use a high res capacitive plate etched into a
piece of silicon like a big chip die. But the touchscreen in your phone doesn't work that way.
Here's a clip from one of the more popular "iPhone fingerprint reader" ad copy:
"If you want to fool your friends and co-workers into thinking your iPhone is a sophisticated fingerprint scanner, this is the application for you.
This application simulates the scanning of fingerprints, the verification of fingerprints against known good fingerprints, and granting of access to
You select the outcome of the scan by briefly touching the refresh control button. Click it once and all fingerprint scans are "access denied",
click it again and all scans are "random"; approved or denied. This allows you to scan your fingerprint and get "access granted", then touch the
control button as you hand the device to friends and family, then watch their reaction when they get "access denied" to their fingerprint scan. The
Random mode is fun at parties and other social functions.
This fingerprint scanning application is for entertainment purposes only and does not actually provide fingerprint scanning capability to your iPhone
or iPod Touch, although only you will know."
Besides which, if you're packing the phone around, they know where you are anyways.
