Thanks! It's very relevant. I was shown something similar months ago and I can't seem to find the link. But it certainly opens up possibilities. The only thing that made me remember the older video was that it can power devices. NFC tags are only like 30 cents each as well. This was the route we were most interested in. I just couldn't remember the name. You can do all sorts of things like tap the mini to bring up profile info and related rules. Lifting it might show firing range.
