QR Code, a two-dimensional bar code storing addresses and URLs, is a widely used technology in Japan and elsewhere that can be scanned with camera phones equipped with the appropriate reader.
It's likely to gain ground quickly in the U.S. now that Google has sent out a QR code to 100,000 of the most popular companies in its Local Business Center. When those companies display the QR code, customers can use code-scanning applications on their iPhones and other devices to retrieve the firm's individual Google listing.
The only problem is, many of those QR code-reading apps for the iPhone just don't do a good job. That prompted me to sift through more than a dozen QR code readers to find some of the best. I came up with four.
QR Code it up
NeoReader NeoReader is one of the most useful apps in this roundup. The program is simple, it's intuitive, and it does a relatively good job of reading QR codes.
NeoReader is an extremely simple app. When it's open, you need only to point your iPhone's camera at the QR Code, click the scan option, and you're all set. Within a few seconds, the app delivers the unique content directly to your iPhone. It works with QR (obviously), as well as Data Matrix, and Aztec bar codes. To ensure the app is working properly, you can even go to NeoReader's home page and scan the QR Code examples to see if it's returning the right results. But beware that the application works best on iPhones running OS 3.0 or higher. NeoReader is free, so it's worth trying out.
Optiscan Optiscan's developers say the application is the fastest QR Code scanner in the App Store. That's not necessarily true. But it's certainly quick.
Overall, Optiscan is a really nice QR Code reader. The application is able to capture QR codes on monitors, paper, and other places where you might find the code. Upon scanning a QR code within the app, you can view the company's QR code information. You can also save that data for later, so you don't have to come back to the QR code every time you want to view it. Even better, Optiscan allows you to share QR codes with others. It's a full-featured app that should satisfy most users. It costs $1.99.… Read more
