Using a QR Code

What is this?

If you’re not sure what you’re looking at, you’re not alone.

That black and white mess is called a QR code (for quick response). If you have a smartphone, you can download a free QR reader to it, then point it at the image to decode it.

In this case, you’d see my contact information, which you could then add to your contacts with a tap (or click, or spin of the wheel).

Wired magazine, among others, has used them for a while, and it goes something like this:

You finish reading an article and notice the QR code at the bottom. You pull out your phone, scan the code, and suddenly your phone is showing you a link, text, or some other information that you never would have seen otherwise.

Often, these codes are on ads, and the information is some kind of special deal, or just more detail about the product.

Why is this great?

Neil Perlin, at Hyper/Word, points out lots of good ways that tech writers could use QR codes, so rather than repeat them, I’ll send you his way.

Note: Neil mentions creating QR codes using Flare. You can probably use your free QR reader to create your own QR codes on your phone (I use QuickMark), or search the Web for free QR Code Generators.

Here’s the link to his site:

Oh, which brings me to another point. Until this stuff becomes ubiquitous, I wouldn’t put anything essential in a QR code unless it’s also somewhere else!
