# How to Generate Event Check-In Codes with OpenClaw

OpenClaw generates QR codes at scale for operational workflows that require consistency and volume. Batch-create codes for entire product catalogs, event ticket sets, multi-location WiFi networks, or payment link collections in a single structured request. The output is formatted for direct integration into print production pipelines, packaging design tools, or automated deployment systems, making it straightforward to generate hundreds of codes with consistent formatting and verified scannability.

## Setup

openclaw mcp add toolrouter -- npx -y toolrouter-mcp

## Steps

1. Connect ToolRouter: openclaw mcp add toolrouter -- npx -y toolrouter-mcp
2. Ask OpenClaw: "Generate a QR code for event check-in at /checkin/main using qr-code-generator"
3. OpenClaw creates the QR code
4. Request additional codes for different sessions or venues
5. Add codes to confirmation emails and printed materials

## Example Prompt

```
Generate check-in QR codes for our 3-day conference. One code per day linking to the daily check-in page.
```

## Tips

- Generate fresh QR codes for each event to prevent code reuse
- Test codes on multiple phone cameras before distributing at scale
- Use URL shorteners for cleaner, more reliable QR codes
