Audio Link vs NFC
NFC needs a phone to touch a tag. An Audio Link reaches everyone who can hear the sound, at once, with nothing to touch.
Side by side
| Aspect | Audio Link | NFC tag |
|---|---|---|
| What people need | To hear the sound | To tap a tag with their phone |
| People at once | Everyone within earshot | One at a time |
| Hardware | Speakers you already have | A tag at every spot |
| Works on | Phones with a supported browser | Phones with NFC turned on |
| Change the destination | Yes, without new audio | Depends on how the tag is written |
Honest limits
NFC is dependable at contact range and needs no sound. Audio Links depend on volume and room noise.
