# How to Generate Event Check-In Codes with ChatGPT

ChatGPT turns QR code generation into a guided process where you describe what you need and receive the right code type with helpful context. Whether you need a marketing URL code, a WiFi access code, or a digital business card, ChatGPT explains the options, generates the code, and provides practical recommendations for print sizing, placement, and testing. The conversational approach is especially useful for teams new to QR codes who want to understand best practices alongside generating the actual assets.

## Setup

{"mcpServers":{"toolrouter":{"command":"npx","args":["-y","toolrouter-mcp"]}}}

## Steps

1. Configure ToolRouter in ChatGPT
2. Ask: "Generate a QR code for our event check-in URL using qr-code-generator"
3. ChatGPT creates the QR code image
4. Request: "Generate separate codes for each session track"
5. Download all codes for badge printing and email distribution

## Example Prompt

```
Generate QR codes for 4 conference tracks: Engineering, Design, Product, and Marketing. Each links to its track-specific check-in page.
```

## Tips

- ChatGPT can create a table mapping each QR code to its purpose and URL
- Ask for codes in specific dimensions for badge printing
- Request a master list of all generated codes for your event team
