Apple Inc.’s (NASDAQ:AAPL) extensive supply chain appears to be working to bring Touch ID to the next-generation iPhone, iPad Air and iPad Mini.

Taiwan Semiconductor Manufacturing Company (TSMC) has provided a delivery of Touch ID fingerprint sensor assemblies that are expected to make their way into the iPhone 6, iPad Air 2 and the next-gen iPad Mini, sometime in April, according to China’s Cecb2b, an electronic component information website. While this information is currently unconfirmed, Cecb2b cites sources inside Sazhou Crystal Semiconductor Technology Co. and Xintec, both subcontractors of TSMC.

Back in February 2014, Apple had reportedly been working to shift some of its manufacturing contracts away from Samsung (OTCMKTS:SSNLF), including the manufacturing of their upcoming A8 processor, which is expected to debut in the next set of devices released by Apple.

These latest rumors fall in line with a research note released by KGI Securities analyst Ming Chi-Kuo, who expects Apple to release its next set of products during the second half of 2014.

While we wait to see if the iPad Air 2 and iPad Mini 2 will actually contain Touch ID, developers continue to turn their attention towards the software behind the devices as Apple’s World Wide Developer Conference (WWDC) approaches this June.

However, no new devices are expected to be unveiled during the developer conference from the Cupertino, California company. Instead, many have cited recent staff changes as a signal that Apple is planning to focus their attention on the rumored overhaul to Mac OSX, version OSX 10.10.

While Mac OSX is expected to take center stage, previews for iOS 8 are also expected to be present during WWDC. Many features are rumored for the successor to iOS 7, including several health related apps packaged in a Passbook-like app called, Healthbook. This shift towards fitness and health related applications have also fueled rumors that Apple is working on a wearable as well, which has been widely called the iWatch.
