Pairing by NFC

Many audio systems are now accessible via bluetooth, but many do not have the NFC to pair this system immediately for short distances and connections with the most publicized application that enables contactless payment, a simple tap on the motomachin to pair the devices. On the side of the transmitter are the most smartphones equipped for NFC devices. So just once to pair your smartphone with this Motorola for a connectable audio output to any amplified audio system (mini jack). It must also connect the Bluetooth receiver to a power supply (included) or in the classical form of mini-transformer or by connecting to a battery charging such, it works too.
The Moto Stream is indicated as being able to connect to five sources simultaneously, I do not personally see the value, I much prefer the opposite: we can connect 5 Moto stream to a single source of Bluetooth, it which allow myself to create a common atmosphere at home from the smartphone connected to Spotify & co or Nas..et reusing speakers (amplified) already present here and there in the house.
A good device but which undoubtedly is in no way an innovation, we have already known elsewhere this can be extended to a Bluetooth audio system old formula. Too bad we can not connect the network motorola gadgets ..
