Hacker News Reader

You could place a sticker over the reader/home button to block covert reading.

you accidentally touch it one time without cover - done. And all the stores where people come and try the devices... (personally as an immigrant i already have my fingerprints on file, so i have nothing to worry about, it is just very amusing to see how another couple of billions would be gathered as well once Android phones replicate the feature :)

Welcome to the Total Information Awareness world.

It takes 30-60 seconds to get a read the first time.

That is a FANTASTIC idea. Get ready to see a kickstarter showing cool button-covers or replacement buttons for those not afraid to open their iPhones.

Or a Kickstarter selling replica Bin Laden fingers.

10,000 of those would keep the NSA quite busy.

(I guess you'd need a live terrorist's finger to replicate though. Those NSA types are pretty smart.)
