📸 3. First Steps – How to take a court-admissible photo

  1. Open QArchiv
  2. Optional:
    • • Enter manually (keyboard or voice input via microphone)
    • • Scan QR/barcode
    → The code is stored in the EXIF UserComment field (prefix selectable, default: GCM_TAG)
  3. Tap "📷 Photo"
    • → The button is always visible – even without code!
  4. Optional: "🎤 Note" for voice description (license only) → stored in Image_Description

💡 Important:

•
No code? → No artificial placeholder (NO_CODE) in EXIF
•
Multiple photos per code possible – sorted by timestamp
•
From V1.40: After "OK" the "Cancel" button disappears – clean UI
•
From V1.512: What you see in the camera preview is saved exactly – no missing edges!

☁️ 4. TrueQ Cloud Integration (New in 1.605)

From version 1.603 you can optionally upload photos directly to TrueQ – with automatic customer assignment.

How the TrueQ connection works

•
Open the FTP settings (gear icon)
•
Select "TrueQ" under "Upload target"
•
Enter your 12-digit TrueQ connection code (format: xxxx-xxxx-xxxx)
•
Tap "Test connection" – the code is validated with the TrueQ API
•
On success: Your name is displayed and the code is saved locally

Automatic Upload

•
With active TrueQ connection, the code is automatically prefixed to every filename
•
Example: a3k9-7m2p-4t8w_A1234_2026-05-08_1430.jpg
•
Upload goes to trueq.de with encrypted connection (FTPS)
•
TrueQ recognizes the code and automatically forwards the file to the correct customer

💡 Advantage: No manual sorting anymore – TrueQ automatically distributes files to the right recipients (Google Drive, AWS S3, Email).

Offline-first remains

•
Code validation happens only once during setup
•
After that QArchiv works offline again – the code is saved locally
•
You can switch back to "Standard FTP" anytime
