QR-log Bridge Offline Diagnostic Transfer
Offline transfer for service-critical environments

Transfer data when nothing connects.

Move logs, diagnostics, and service bundles from a product screen to iPhone or iPad. No VPN, no cloud, no cable.

Up to 200 kbit/s on-the-fly transfer
Simple customer-guided capture
Medical device support ready
Why it works

A simple fallback when standard transfer fails.

Performance
200 kbit/s

Peak on-the-fly throughput.

Simplicity
No specialist handoff

A familiar mobile workflow instead of USB export.

Connectivity
Local-first by design

No cloud, VPN, or support tunnel.

Deployment
Works in constrained sites

Where permanent links are blocked.

How it works

Encode, scan, reconstruct.

1

Encode

The encoder turns the file into a high-density QR stream.

2

Scan

iPhone or iPad captures the stream with the camera.

3

Reconstruct

The app rebuilds the file and verifies integrity.

Where it fits

Built for constrained connectivity.

Medical devices

No permanent manufacturer tunnel

Move diagnostics while respecting site restrictions.

Regulated networks

Works where remote support is blocked

No VPN, cloud, or permanent link required.

Offline products

A repeatable service bridge

Useful where removable media is slow or risky.

Technical foundation

Robust transfer, simple workflow.

Integrity

Validated transfer

CRC32, SHA-256, and parity recovery.

Scanning

Tuned for the camera

Lens choice, zoom, and tap-to-focus.

Payloads

Any file type

Logs, PDFs, ZIPs, and binary files.
