## What is LinkRay Scanner?

LinkRay Scanner reads LinkRay (HikariID) optical IDs transmitted by LED lighting. Point the camera at a participating light, and the app decodes the ID that light is broadcasting and shows what it is linked to.

WHAT IT DOES
- Decodes LinkRay IDs from LED lights using the rear camera
- Looks up each scanned ID and opens the content mapped to it
- Keeps an on-device log of what was scanned and how the camera performed
- Uses a published camera profile for your iPhone model

HOW IT WORKS
A LinkRay light carries a short numeric ID by flickering faster than the eye can see. The app samples that flicker through the camera and recovers the ID. Recovery depends on the precise timing of the camera sensor, so the app relies on a camera profile published for your specific model.

WHAT YOU NEED
- A LinkRay-equipped light to scan
- A network connection: the app loads its screens and the content for each scanned ID from the LinkRay Scanner server
- A published camera profile covering your iPhone model

ON MEASUREMENT
This app decodes using camera profiles that already exist. It does not measure or calibrate new profiles.

PRIVACY
Video from the camera is processed on the device and is never uploaded. Diagnostic records of a scan - your device model, decode timings and the result - are sent to the LinkRay Scanner server so that profiles can be improved. The privacy policy at https://linkrayscanner.piecefuture.duckdns.org/privacy explains what is kept and how to have it removed.

## Version history (last 5 releases)

### 1.0.4 — 2026-10-11

• Scanning starts as soon as the app opens, with an aiming box in the camera view
• A steadier, clearer camera view: fixed focus, no flicker or flashes as the camera starts
• Staff tools now sit behind Admin login, with password reset by email

### 1.0.3 — 2026-10-09

Anti flicker and anti infinity focus for camera view

### 1.0.2 — 2026-09-27

Camera view on iPhone: the Configure tab now has a Test scan card with a live camera view, and the camera shows while an iPhone measures or calibrates itself, so it is easy to keep the LinkRay light in frame.
Calibration now also works with LinkRay lights running either of the two carriers in use (5427 Hz and 4120 Hz).

### 1.0.1 — 2026-09-26

iPhone calibration: iPhones newer than the scanner's built-in camera table, such as the iPhone 18, can now calibrate themselves from the Configure tab and publish their camera profile, so every phone of that model can scan. iPhone 17 and earlier are unchanged.
The published camera profiles list now shows Android and iPhone models separately, each with its own upload and download.

### 1.0 — 2026-09-20

No release notes.
