When normal transfer is blocked, QR-log Bridge replaces USB handoffs and late collection with guided mobile capture.
QR-log Bridge
Detailed Description
Offline transfer for service and diagnostics
A practical bridge when connectivity is not available.
QR-log Bridge moves diagnostic packages from a product screen to iPhone or iPad when network, VPN, cloud, or USB handoff are not realistic.
Why QR-log Bridge exists
Support should not stop because a device is offline.
Many products operate where diagnostic connections are blocked by policy, segmentation, or offline use.
Operational outcome
- Faster time from incident to diagnostic visibility
- Less coordination around USB or local extraction
- Better preparation before the first service visit
- Higher chance of first-visit resolution
Service scenario
A strong fit for medical device service.
Downtime is expensive. Earlier technical context improves dispatch quality.
For the customer
Simple, guided capture
A familiar mobile workflow replaces slow extraction.
For support
Earlier technical clarity
Engineering receives better context before dispatch.
For service operations
Better dispatch quality
The service engineer arrives better prepared.
Transfer model
How the bridge works at a high level.
A device displays a visual transfer stream. The app captures it and makes the resulting file available locally.
Step 1
Prepare the data
The source system prepares service data for visual transfer.
Step 2
Capture with iPhone or iPad
The app captures the stream live or from a short recorded clip.
Step 3
Receive locally
The resulting file is made available on the device for review or sharing.
Step 4
Support with context
The payload gives service teams earlier diagnostic context.
Platform concept
Designed as a product workflow, not a manual workaround.
Source-side component
Payload preparation
Prepares service data for visual transfer.
iOS receiver
Live capture and Video Decode
Receives live streams or recorded clips and stores the result locally.
Reliability layer
Designed for imperfect capture
The workflow is built for practical camera distance, motion, and display conditions.
Operational UX
Built for real support use
Guided capture, received files, and sharing support real service workflows.
Where it fits
Useful wherever transfer paths are constrained.
Medical devices are the clearest use case; service-heavy products often share the same constraints.
Medical devices
Diagnostics without always-on connectivity
For environments where downtime matters and connectivity is constrained.
Laboratory and analytical systems
Controlled environments with strict policies
For sites where remote access is restricted or slow to approve.
Field service products
Simpler escalation from the installed base
Turns difficult handoffs into a guided mobile workflow.
Regulated deployments
A fallback that respects local rules
A practical bridge where policy blocks conventional connectivity.
Technical profile
Capabilities that make the simple workflow reliable.
Performance
Transfer rates up to 200 kbit/s
On-the-fly throughput with normal and 2x2 QR layouts.
Payload types
Logs, files, and binary data
Moves PDFs, ZIP archives, images, diagnostics, and binary content.
Operational model
Local-first and infrastructure-light
No cloud, account system, or background sync. Video Decode also supports short recorded QR clips.
