I read this:
With Apple rumored to be attempting to acquire a security solutions provider, a new move by AuthenTec to sell a portion of its business suggests Apple is most interested in its fingerprint scanning technology.
Apple bought this company in July for about 350 million dollars. And it makes me think: if Apple puts a fingerprint sensor on the home button of the iPhone, they could enter the mobile payments industry by the big door. Plus, they already have so many credit cards with one-click purchases on iTunes and the App Store, it really looks like a logical next step.
