The gadget's use of near-field communication, or NFC, reflects Apple's broader ambitions for the so-called iWatch beyond health and fitness tracking, the most commonly cited use. Apple also is expected to add the wireless technology to the next versions of its iPhone, people familiar with the device said, potentially simplifying the process of connecting, or pairing, the two devices.
NFC has been widely rumored for the iPhone 6; however, recent reports have also suggested it will be implemented on the iWatch, perhaps with a secure enclave to store credit card information.
The WSJ also notes that the iWatch will come in two different sizes, corroborating an earlier report today from Ming-Chi Kuo.
The smartwatch would be offered in two sizes, both featuring a curved organic light-emitting diode screen, those people familiar with the device said. It will include sensors to track and monitor health and fitness data, the people said.
Apple is expected to unveil the iWatch on September 9th. Please follow iClarified on Twitter, Facebook, Google+, or RSS for updates.
