Host card emulation (HCE) was invented back in 2012. It was supposed to do for NFC on Android what Apple Pay has done for NFC in the iOS ecosystem. But it’s taken longer, a lot longer, for a robust Android-based NFC capability to get deployed. In this conversation with HCE inventor Doug Yeager, CEO of SimplyTapp, we review how HCE works, what it requires, and take a look at why it’s taken so long to gain momentum. The good news is that momentum is increasing with a growing set of HCE technology providers pushing it forward and, it appears, a pipeline of HCE-based apps on the way.
