You know those little boxes that look like zany microchips that you see on magazine ads and billboards? Yes, of course I’m talking about 2D codes, commonly known as QR codes. You may already know that if you give a 2D code a quick scan with your Smartphone, it will take you instantly to a URL, text, phone number, SMS or vCard. But did you know it’s super easy to make one of those bad boys for yourself?

It seriously only takes seconds to make your very own QR code. I tried it on Kaywa and it was so ridiculously easy that I don’t know why every college student doesn’t have one. My guess is it’s probably because most people don’t know what 2D codes are or what to do with them. If you’re one of those people, don’t worry, it’s super simple. All you have to do is download a QR code reader on your Smartphone, like ScanLIfe, and you’ll be able to scan QR codes. And then you can get going on making one for yourself!

Sites like Kaywa let you customize your design for free, and if you’d like, you can get the paid version to track your code’s performance. With Microsoft Tag, you can add color to your QR code, which is really cool, especially if you’re using a color theme on your marketing materials.

So why would you want to make your own QR code? Well, answer this: Are you a rock star? Have your own business? Leading a club on campus? Selling something on Craigslist? Looking for a job? Adding a simple QR code can transform your flat business card, flyer, or online post into a completely interactive experience! And you can link your QR code to your web site, Twitter, Facebook, Linked In profile, mobile blog or more. Want to learn how to create a mobile blog?
