As someone in cybersecurity, it is handy as a low frequency RFID reader as Android phones only support higher frequency. Having something compact and in a single unit (compared to a Proxmark) makes it easier to 'grab-n-go'. It is neat to show people how insecure common access control systems are.
I've also used it as a universal remote more than a few times on devices that didn't come with a remote. The App running on a phone makes it somewhat easy to transfer new remote templates to the Flipper over Bluetooth.
It also comes in handy as a serial adapter as it has GPIO pins you can connect to things (UART headers).
The RF transceiver is also cool to capture RF remotes (garage doors, overhead fans, etc.) and replay them.

Do you mean the non IR kind?
