Audio Handshake
Audio Handshake App for Sharing Links with Sound
Share a profile or link using your phone speaker when camera alignment, NFC taps, or printed cards slow the moment down.
Short answer
Audio Handshake is Qrblox's sound-based sharing feature. It lets nearby phones receive a profile or link through a short audio signal instead of requiring a camera scan, NFC tap, or Bluetooth pairing.
How it works
A simple path from the real-world QR moment to a saved, useful result.
Step 1
Choose the profile, handle, or link you want to share in Qrblox.
Step 2
Use Audio Handshake to broadcast the data with sound.
Step 3
Nearby Qrblox users can receive the shared information and continue the interaction after the moment passes.
Why use Qrblox
Qrblox is built for QR scans that need more context, memory, or flexibility than a one-time camera open.
No camera alignment
Helpful when QR scanning is awkward in low light, crowded rooms, or quick introductions.
A digital business card feel
Use sound to share profile details during networking moments without handing over paper cards.
Fallback to QR scanning
Qrblox supports both Audio Handshake and regular QR scanning from cameras, photos, and screenshots.
