Apple is acquiring AuthenTec for around USD 350 million.
AuthenTec deals in fingerprint-authentication and encryption security technology.
We can only assume that they are planning to use these technologies on their iOS devices.
It would be interesting to see if this also makes it to their MacBook range of laptops in the future.
Samsung recently revealed that they were considering using technologies provided by AuthenTec on their mobile devices. Looks like they would have to discard those plans.
