> Note: You may need to increase your iPhone volume, since Dash Button uses ultrasonic tones to sync with your iPhone during setup. If prompted, drag the volume slider to the recommended level, at or above where it says Best.
I actually wrote a library that does this, FSK to WAV and back is just a few lines of code, and fairly reliable. There are even Javascript libraries that can do it.
I think it probably is real, it just shouldn't be. :-/
No reason it shouldn't be. Brilliant idea: put a "reorder consumable product" right where you will be the moment you realize you need to reorder a particular consumable product. Running low on laundry detergent? TP? fabric softener? trash bags? push button. You walk away from that location, you'll immediately forget you needed to order (which means drive to store or fiddle with browser). Devices can be built dirt cheap now: button, minimal wifi, ease setup via (yes) nigh-unto-free microphone. App gathers requests, confirms them (my first thought was "great, kids sit there pushing button and order 137 bottles of Tide"), done, product arrives in 24/48 hours.
