QR Builder is a simple, modern interface to building custom QR Codes for you and your brand. Customize nearly every aspect of your QR Codes to reflect your personality or brand, all while retaining complete control over how you track QR Code usage.
I acutally used this QR Builder for my booth at a Python conference. It was helpful for sharing with attendees. It worked as promised, and was very low-hassle to configure. I liked how it is customizable and also thought the pricing seems fair. It's really useful to have a tool to bypass building this stuff out myself.
