Clumsy and unreliable, bordering on dangerous.
Imagine trying to leave in a hurry and having to press a button and wait for a device to cycle to unlock the door, having it re-lock the door, and then needing to do it all over again in order to be able to open the door and leave. At the very least, that’s a fire hazard.
Plus, the idea of being forced to install somebody’s mystery software on your phone with no control over what sort of data is being collected? Obnoxious and unacceptable.
