What is an Audio Handshake?

An Audio Handshake is Qrblox's sound-based sharing feature. It uses your phone speaker and microphone to exchange profile links, contact details, and other data without needing a camera scan or NFC tap.

How does an Audio Handshake work?

Qrblox converts your profile or link into a short sound signal. Another nearby device listening with Qrblox can decode that signal and open the shared information instantly.

What can I share with Audio Handshake?

You can share your digital profile, contact details, links, and other compact data payloads. It works like an audio business card and can also support audio QR-style sharing flows.

Why use Audio Handshake instead of a normal QR code?

Audio Handshake is helpful when scanning is awkward or impossible, like in low light, crowded spaces, or fast networking moments. It removes the need for line-of-sight alignment and makes sharing feel more seamless.

Does Audio Handshake replace QR codes?

No. Qrblox supports both. You can use Audio Handshake and Audio QR for camera-free sharing, then still scan QR codes from printed surfaces, screenshots, and photos in your gallery whenever that is more convenient.

Is Audio Handshake good for business cards and networking?

Yes. Qrblox can work like an audio business card app, making it easy to share your profile at conferences, coffee chats, events, and quick introductions without paper cards or awkward scanning.

Can you scan a QR code from a picture?

Yes. Use Qrblox to scan QR codes from screenshots, saved pictures, and images in your gallery.

What do I do to open a QR code from a picture?

Using the Qrblox app, simply upload the picture to the app on the top left of the Scan tab to open the QR code from a picture.
