Would presumably use tech acquired from AuthenTec
The iPhone 5S will implement both NFC and a fingerprint sensor, the China Times alleges. A Taiwanese company, Chipbond, will reportedly provide touch display drivers and some other necessary parts. The fingerprint system is expected to operate in service of the NFC, providing extra security for mobile payments. It should also be based on development work by AuthenTec, a company Apple bought out last summer explicitly for its fingerprint technology.
NFC support has long been rumored for Apple devices, but failed to materialize in either the iPhone 4S or 5. Some form of fingerprint sensor is effectively guaranteed, but whether or not Apple can implement it in time for a 5S will be dependent on factors such as design hurdles, profit margins, and supplier readiness. It's believed that Apple may integrate sensors into the Home buttons of all future iOS devices.
