With its chief rival widely recognized as the key pioneer behind mobile fingerprint scanning, Samsung sought to assert itself with a different modality when it announced the Galaxy Note7 smartphone last year. It was to become the first globally available, mass market smartphone to feature iris recognition for user authentication, and to kick off a new revolution in mobile biometrics, until disaster struck and the Note7 saw a total recall due to a fire hazard.

Samsung didn’t give up, however, and firmly delivered mobile iris recognition to the mass market at the start of this year with its acclaimed Galaxy S8 and S8+ devices. Still, whether iris scanning would go mainstream the way fingerprint scanning did remained an open question, with those devices being virtually alone on this new frontier.

Several months later, it’s increasingly clear that a larger trend is taking shape. Here are some of the signs:
