Are you using your mobile phone like it’s 1999?
TECHNOLOGY Popular in Japan since the '90s, Quick-Response (QR) codes are gaining popularity in the United States and elsewhere. Embedded within a QR code is a hidden message. Usually it's a shortened URL. But it can contain up to about 90 alphanumeric characters within a standard square. As character count increases, the pattern becomes denser and more challenging for low-resolution scanners to decipher.
QR codes can also contain vCard data, allowing users to automatically add contact information to mobile devices.  QR codes can craft an email message or Tweet. A Korean market displays virtual supermarket shelves in subways, allowing customers to use the idle time waiting for transportation to shop via QR codes without entering a store. Groceries are delivered to their home. 
Is Your Phone Smart Enough To Save You Money?
If you already own a smartphone or digital tablet, the biggest hurdle is behind you. In fact, most QR reader apps are free. Sometimes additional features can be added for a few bucks. Current smartphones have high resolution cameras, making it possible to decipher small QR codes on business cards or in magazines.

Generally, you will not need to press a button; the image is processed as soon as the code is recognized. Depending upon settings, the app may immediately open a URL, import vCard data or display a picture. It is also possible that the content is previewed for confirmation before performing an action.
