Salmon Dayoff Scanner - iOS

Notice

This is the QR code scanner app used on all gates of Hangzhou Dianzi University in 2020, before the transition to face recognition.

Private information has been replaced with [REDACTED], which in many cases breaks the code from running, so if you decided to use, please search for [REDACTED] and replace with correct values accordingly.

This code is now released in MIT.

Note that the file CodeScannerView.swift is a modified copy from twostraws/CodeScanner, thus the author's license (which is also MIT) applies.

---

This version of scanner is for specialized deployment.

Configuration

All configuration of this app is done via QR codes.

The QR code should contains a string of JSON.

Note that actual JSON does not allow comments.

{
  "token": "xxx", // The Lemon token for that matter.
  "name": "Test Gate", // Gate name, for display in app only.
  "direction": 1, // 1 for out, -1 for in.
  "stats": { // Optional, for resetting counts on the bottom of screen.
    "success": 0,
    "fail": 0,
    "error": 0
  }
}

For safety, when a QR code containing such a JSON string was shown to scanner, it would ask for iOS authorization. So proper authorization should be in place on that device.
