RF devices are already ubiquitous, the technology and applications keep growing, and there's emerging opportunities for innovative applications.

FWIW, I "funded" the Kickstarter for Flipper Zero because my startup was doing something a little innovative with various kinds of RF tags, to help solve a significant societal problem. (Which, besides what we could've contributed to a country in monetary value of our company, the application domain had significant implications for national economies, as well as for public safety. All things that lawmakers care about, in addition to reducing auto thefts.) We had Android diagnostic software, plus bespoke iOS apps with NFC that I wrote, but a Flipper Zero would've helped me work better and faster at some things.
