I'm in the industry and I have to agree here. All of the devices we develop and use (third-party) either already have this capability built-in to the device or are working on it right now.
It's a tough space.. margins on these hardware devices are thin already, and sometimes negative as they are simply loss leaders hooking in users for long-term saas payments, so in our case, it's cheaper to build it in-house.
Good luck, however!
