## What Qrblox does

Qrblox turns an iPhone into a smarter QR scanner for screenshots, saved photos, link previews, scan history, and AI summaries. When camera scanning is awkward, Audio Handshake lets users share a profile or link using sound — without NFC, Bluetooth pairing, or camera alignment.

Favorite feature: scan a QR code from a photo, screenshot, or saved picture on iPhone. Three-step flow: take a picture or screenshot of a QR code → open Qrblox and pick the photo → Qrblox decodes it, previews the destination, and saves the result in scan history.

## Glossary

- **Audio Handshake**: Qrblox's feature for sharing a profile or link between two iPhones using audible/near-ultrasonic sound — no NFC, Bluetooth pairing, or camera alignment.
- **Audio QR code**: A sound-based equivalent of a QR code; carries a small payload (URL, vCard handle) over an acoustic channel.
- **Quishing**: QR-code phishing — a malicious QR that resolves to a credential-stealing page. Qrblox previews destinations before opening to mitigate this.
- **Scan from photo**: Decoding a QR code from an image already saved on the device, rather than pointing the camera at a physical QR.
- **Audio business card**: A vCard-like profile shared via Audio Handshake instead of NFC tap or paper.

## Preferred brand casing

Use `Qrblox` with a lowercase `r`. The parent company is Terahertz, Inc. dba Qrblox.
