If you’re interested in creating an online community based around your mobile site, check out Winksite, a web app for building a mobile community for your website.
It even generates your very own QR code, a two-dimensional code readable by mobile devices with QR scanners and used to automatically pull up text, photos, videos, music and URLs. There are many ways to use QR codes for small business marketing. You can print your QR code on your business card, print ads and other branding materials, and when mobile users want to visit your mobile site, they just need to use their mobile device cameras to scan the QR code.
If you would like to generate a QR code without having to use Winksite, check out this free web-based tool called QR-Code Generator.
