You have probably seen them out shopping, or in the paper, and almost anywhere. Those weird little checker boxes that people seem to randomly put on everything. Those are actually QR codes. What they allow one to do is scan them with a QR code app on your smartphone, such as a Droid, iPhone, etc, and it will open up a website, or possibly just some text for a message. This is really great if you are in Best Buy and want to get more information on a laptop, you can scan the QR code with your phone and it will take you to a website with the information on the laptop.
To scan a QR code first you need a smart phone with a QR code app. There are tons of them out there, in both the Droid and Apple App Store. I have an iPhone and have used Red Laser, QR HD, or ShopSavvy. Basically make sure you find a QR code scanner app that you like, and you are in business.
But let’s take it a step further, let’s say that you want to create a QR code for a website, or a message to passerbys. There are many sites out there that will generate QR codes for you if you give them the message or website, such as Kaywa QR Code Generator. In fact if you use the URL shortener Bitly as I talked about in an earlier post, you can add a .qr at the end of the URL and it will give you the QR code for that site. Such as http://bit.ly/psd4Gl.qr. Once you have your QR code generated you can print it out, add it to signs, fliers, where ever you want people to quickly scan and open your URL or message.
So that is the quick and dirty introduction of what a QR code is. If you are looking for a way to reach and audience of people, or just want to do a fun treasure hunt, maybe take a look at using a QR code. Because whether you like them or not, they are out there and are not going to go away anytime soon.
