Direct Scan to URL (DSU)

What is Direct Scan to URL (DSU)?

Direct Scan to URL (DSU) is a feature in CodeREADr mobile apps that allows scan data to bypass CodeREADr’s servers, posting directly to your server. Similarly, your server can send a response directly back to the app. This approach ensures enhanced data security and optionally enables seamless integration with local area networks (LANs), especially useful in scenarios with firewall restrictions or unstable Internet connectivity.

Key Benefits of DSU

• Data Privacy: No scan or response data is stored on CodeREADr’s servers.
• Reduced Latency: Instant scan responses with minimal delays.
• Offline Functionality: Supports offline operations with Auto Sync for post-scan processing.
• Local Network Support: Ideal for environments with limited or restricted Internet access.

How to Use DSU: Two Options

Option 1: Server Responds Directly to Scans

• Set Up the Service:
  • Choose “Scan to Third Party Server” when creating the service.
  • Select “Skip our server and go directly to yours”.
  • Enter your destination URL.
• Scan Flow:
  • The mobile app posts the scan data directly to your server (local or cloud-based).
  • Your server sends a response directly back to the app.

This setup ensures secure and real-time scan processing.

Option 2: Offline Validation or Record Scans

• Create an On-Device Service:
  • Opt for a validate or record-only service type with Auto Sync enabled.
• How It Works:
  • App users see scan results (e.g., valid, invalid, duplicate) instantly on their device.
  • Once connected, the scan data is sent to the receiving server, requiring a DSU response to clear the record locally.
• Advantages:
  • Instant feedback with no LAN or Internet latency.
  • Fully functional even in offline mode.
