QR Code Types
Our generator supports all major QR code types including URL, text, email, SMS, phone, Wi-Fi, vCard, location, event, and UPI codes. Each type is designed for specific use cases and contains different information formats.
URL QR codes contain web addresses and automatically open the website when scanned. Text QR codes contain plain text that displays as a message when scanned. URL codes are great for linking to websites, while text codes are perfect for sharing information, instructions, or messages.
Wi-Fi QR codes contain your network's SSID, password, and encryption type. When someone scans the code with their smartphone, it automatically connects to your Wi-Fi network without manually entering the password. This is especially useful for guests or customers.
