# How to Generate Event Check-In Codes with Claude

Claude generates QR codes as part of an interactive terminal session where you can iterate on parameters, test different configurations, and batch multiple codes efficiently. Create marketing QR codes, WiFi login codes, and digital business cards in sequence, adjusting each one based on the specific use case and discussing the best settings for print size, error correction, and visual contrast. The hands-on workflow gives you full control over every code you generate while keeping the entire batch organized.
