Browser Extension

EHR Scanning Relay Bridge

Chrome/Edge extension that connects your iOS device's barcode scanner to your EHR system via a local relay server.

What It Does

This extension bridges your iOS device's camera (for barcode scanning) with your browser's EHR system. When you scan a barcode using the companion iOS app, it automatically inserts the scanned code into the currently focused field in your EHR.

Privacy First: All communication happens locally on your device via localhost. No data is sent to external servers or third parties.

How It Works

1

Install Extension

Add the extension to Chrome or Edge browser

2

Start Relay

3

Scan Barcodes

Privacy & Security

No Third-Party Data Transfer

All data stays on your local network. The extension only connects to localhost:8787.

Single Purpose Only

The extension does one thing: inject scanned barcodes into focused input fields.

Not Used for Credit/Lending

This extension is solely for healthcare barcode scanning workflows.
