If you happen to see my car tooling around, you'll see this cool magnetic bumper sticker.(Actually it's on the side panel of my car as the jelly bean shaped hatch doesn't have a wide enough metal space to attach the magnet) Isn't it cool? But you're asking yourself, yeah, it's colorful but what is it? Embedded in the pixelated turquoise square is a QR code. It's like a bar code you can scan with your Smartphone. The QR code stores a URL and some other information. Scanning the code of the bumper magnet, the code will send a special offer to your phone. The promo code can be used by phone or online. Scan the code now, and you'll be able to get $5 off a Fall class, like Practical Calligraphy. During the year, you'll be able to scan the magnet and other promotions will be offered.

So how do you use your smartphone to scan the code? Yup, there's an app for that. You'll need to download NeoReader to your phone. Point your camera to the bar code, click the scan option and voilà.
