QR-log Bridge logo
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
Proof points

A simple fallback when standard transfer paths fail.

Built for isolated devices, controlled networks, and support teams that still need actionable data.

Performance
200 kbit/s

Current implementation peak, depending on payload and scan conditions.

Operational simplicity
No specialist handoff

Customers use a familiar mobile workflow instead of USB export.

Service readiness
Better first visit preparation

Service arrives with context, not guesswork.

Deployment fit
Works in constrained sites

Useful where site rules block permanent diagnostic links.

Why teams adopt it

Simple transfer without guaranteed connectivity.

Best fit: medical device support, controlled sites, offline products, and urgent escalation.

Many products cannot maintain a permanent support connection. QR-log Bridge turns that gap into a guided mobile transfer.

Best-fit environments
  • Medical devices and hospital-based service workflows
  • Products deployed in regulated or highly segmented networks
  • Systems where removable media is slow or risky
  • Product lines that need a repeatable support bridge
How it works

One clear flow: encode, scan, reconstruct.

Encode, scan, reconstruct, act.

1

Encode the payload

The QR Payload Encoder renders the file as a high-density QR stream.

2

Capture with iPhone or iPad

The app scans the stream with the camera.

3

Reconstruct and act

The app rebuilds the file and verifies integrity.

Integration profile

Fits wherever connectivity is constrained.

Medical devices are the clearest fit; the same model works for support-heavy products in restricted environments.

Medical devices

Support data without a permanent manufacturer tunnel

Move diagnostics while respecting site restrictions.

Service tools

Simple workflow for field teams and customers

Guide users through capture without specialist hardware.

Regulated deployments

Designed for constrained connectivity

Works where VPN, cloud, or remote support are blocked.

OEM product lines

Integrates into multiple service narratives

Position it as a service bridge or premium support feature.

Technical foundation

Robust transfer, simple user workflow.

Integrity

Validated transfer

CRC32, SHA-256, and parity recovery protect the payload.

User experience

Optimized for practical scanning

Lens selection, zoom, tap-to-focus, and iPhone/iPad layouts.

Payload flexibility

More than simple text transfer

Move logs, service bundles, PDFs, ZIP archives, and binary files.

Operational fit

Complements existing service processes

A faster fallback when the standard path is blocked.
