I don't know what kind of designs they're using for this dynamic pricing shit, but I do know about the Flipper.
They are really solid hardware with a bit of a gimmicky presentation standing between it and an incredible community. It's extremely flexible and provides raw access to just about every kind of infrared/RF/NFC/wireless/wired protocol you could ever imagine trying to hook it up to. Many of the aforementioned protocols have limited or no security, relying mainly on security through obscurity and cost-prohibitive and restricted-access hardware to control other devices using this protocol. And the Flipper is comparatively non-cost-prohibitive and supports being configured by software to do exactly the same things as most of the cost-prohibitive, restricted-access technology that gatekeeps these protocols. You can do the math and put the pieces together, I hope.
I can tell you mine is sitting in front of me on my desk right now ready to go, I don't intend to use it often but it's useful to have when I need it. I'm not sure what else to tell you.
