ChatGPT's image generator draws pictures that look like QR codes but don't scan. With its code tool it can sometimes make a real one, depending on the libraries in its sandbox.
The Barcode server turns text or a URL into a QR code as SVG, and also makes WiFi join codes, vCard contact codes and EPC payment codes a euro banking app can scan. The free tier gives 20 codes a month. PNG output is Pro. To try it in ChatGPT on the web, where your plan or workspace allows custom MCP servers, get a free token at mcp.zovo.one/mcp/connect and add mcp.zovo.one/mcp/barcode/t/<token> as a server with No authentication. We haven't tested this in ChatGPT yet.
