QR Codes are a popular type of two-dimensional barcode, which are also known as hardlinks or physical world hyperlinks. The quick response (QR) barcodes can store a variety of text information, be read very fast, even upside down and can be scanned from a screen, a newspaper or magazine, flyer or even a billboard.
QR Codes store text, which can be:
• A website address
• A telephone number
• An SMS Message
• Contact Details (VCARD)
• A Google Map
• A Facebook or MySpace Profile
QR codes can be read by scanners or camera equipped mobile phones. Many Nokias have the software built in, if you have an IPhone, you can download free QR barcode readers at the ITunes store.
QR codes can be placed in magazine ads or on outdoor billboards, pointing to further information about products. These hyperlinks on paper help integrating paper into the information and marketing media mix, they can be found on books, McDonalds packaging, pointing to information about your burger and there is even an example where codes on a cemetery point to information about people. Another very cool application is Starbuck’s loyalty IPhone app.
