NFC-enabled Audio System

NFC-enabled Audio System

Tap-to-pair has become a common habit when connecting an NFC-enabled smartphone conveniently to a wireless speaker. Bringing this experience to the next level, even a multi-speaker audio system can be set up with NFC. If all speakers are equipped with an NFC chip, you simply tap one speaker to another to establish the connection. That’s what we call a true wireless stereo system - and it works with any phone, no matter if it is NFC-enabled. The same can be done with NFC-headsets.
