QR codes are everywhere these days - on business cards, restaurant menus, product packaging, and even in museums. I remember trying to create a QR code for my business card and getting frustrated with complicated online tools that required registration or had limited customization. That's exactly why I built the QR Code Generator - to make QR code creation simple and accessible.

Why Use QR Codes?
QR codes offer several advantages for businesses and individuals:
- Easy sharing - No typing required, just scan
