The reader application is the tool that allows the consumer to scan and access the information embedded in the QR code using a smartphone. There are dozens of different reader applications available for the various mobile operating systems on the market today. Many of these applications are free, some are not.
QR codes have the ability to embed calendar events, vCard information, SMS, email addresses—and of course—URLs. I tested many of the applications and most have one thing in common: they are capable of scanning, but not capable of intelligently utilizing the data embedded within the QR code.
