QR codes are finally gaining momentum in the United States, but these square two dimensional bar codes are everywhere in Japan, where they were originally devised to track auto parts by Denso (now Denso Wave Incorporated) in 1994. Smartphone users snap pictures of QR codes on products or advertising, then a reader app decodes and displays the information or link contained in the code. Denso Wave owns the patent, but has chosen not to charge a licensing fee for its use.
Why should you care about QR codes?
For little or no cost, QR codes provide an extra level of communication between you and your customers, and increase your exposure to potential new customers. In just a few seconds, they can snap a picture of the QR code and decode it, to display your contact information or a link to a landing page or a video. Commercial QR code generators can provide you with analytics and customize the design to include your logo, but you will pay a fee for their service. URL shorteners goo.gl and bit.ly create QR codes automatically for shortened links and provide some free analytics. (On goo.gl, click on "details" and on bit.ly, click on "info page.")

QR codes can connect your customers to your content or social media platform instantly. A QR code on your product means that everyone who comes in contact with it has a quick and easy way to find you and buy it for themselves. On your printed material, you can give your customers access to information that wasn't available at the time of printing. Link to a video, a coupon, a Google Maps location, a special offer or an mp3 download.
A QR code on your delivery truck could turn passersby into new customers. On a menu or food packaging, the QR code can link to nutritional information.
A QR code on a power tool can link to a video on how to use it, an online instruction manual or a form for replacement parts and service. On stickers, posters, shopping bags, postcards, tee shirts, tote bags, hats or billboards, QR codes are a cost-effective call to action for your customers.

How Do I Get a QR Code?
There are many "free" QR Code generators, but read the fine print- free code is usually for non-commercial use only. Kaywa is the most popular of these, and it supplies free QR code readers as well. Website Magazine recommends ScanLife for reasonable commercial pricing and quality analytics, and the Google-hosted open source project, ZXing (Zebra Crossing,) which is free and posts no restrictions for commercial use on its no-frills website.
How does it work?

Because 2D codes are read both horizontally and vertically, they can hold more information than a horizontal bar code. The three corner squares tell the code reader which side is up. The chunky pixels create a high contrast image that should be quick and easy to read with a smart phone or iPod Touch (4th generation) and a QR code reader app. How well this actually works will depend on the quality of the device's camera, the quality of the snapshot and the dependability of the code reader app. Smart phone cameras without autofocus may not produce a sharp enough image to be read. The same thing goes for a snapshot taken in low light or while the camera is moving. As smart phone camera quality improves and reliable reader apps are developed for all smart phone platforms, QR codes will undoubtedly be a powerful marketing tool for everyone.
