Conceivably, once someone is checked in, he or she could use the wristband to gain access throughout a facility that has security doors (heck, maybe even to get rid of annoying bathroom keys).

Brivo itself has used the Randivoo system at conferences to help facilitate meetings and for capturing contact information. (Imagine being about to tell that the person who just showed up is way more important that you realized, simply by checking them in.) Odess believes the solution could be appropriate for collecting tickets at concert venues or for member check-ins at health clubs, where someone is liable to be wearing a fitness tracker anyway. Nymi happens to be its first integration of this sort, but other devices could be integrated in the same way, Odess said.

The baseline subscription for Randivoo (which can be used in collaboration with Salesforce, obviously) is $49.99 per month for up to 100 users.

What's the real market potential for applications of this nature? Another wearables and Internet of things market research study by Acuity Group (part of Accenture Interactive) forecasts adoption at 22 percent of consumers by the end of 2015 and 43 percent over the next five years. For perspective, that's pretty much the same saturation rate that smartphones followed.

The big wild card (as usual) is privacy: 80 percent of the 2,000 people surveyed wear concerned about this aspect of the technology. However, half of them also admitted that they would share personal data in exchange for some sort of promotional opportunity or discount.
