QR Codes are Mysteries Unwrapped by I-nigma

QR codes are popping up everywhere these days.  When I first saw them I wondered if they were the spawn of a crossword puzzle and Sudoku grid.  For those unfamiliar with QR codes, they are matrix, or two-dimensional barcodes, and are sometimes referred to as paper-based hyperlinks or mobile tagging.  They are found in magazines, billboards, on business cards or the like.  They are not limited to static surfaces either.  They can also be projected or shown on electronic billboards.  When scanned by a cell camera, they lead the user to additional information about the product, such as web sites, contact information, etc.  For instance, one might read a movie review and see a QR code that sends the user to the actual movie trailer, no typing of URL’s required.

I’ve tried a few QR reader apps, including AT&T’s.  I found it to be slow and frustrating to use.  I much prefer the free app by i-nigma.  It is fast, scans standard barcodes, data matrix and QR codes.  It had no problem with paper or electronic images of codes and quickly launched Safari for the referenced URL.  i-nigma’s (4) QR datamatrix barcode reader is compatible with the iPhone and iPod Touch running iOS 4.0 or later.  For those running older an iOS, they still have a version in the app store which runs on iOS 2.0 or later.

For more information about the history and uses of QR codes, check out the Wikipedia article.
