QR codes are 2D barcodes, short for Quick Response Codes. They are very common in Japan, where it was created by Toyota subsidiary Denso-Wave in 1994 to rapidly scan parts information in their plants. Due to the 2D feature, it can store more information than the typical 1d barcodes.
Since then, several uses have been found for QR codes. QR codes can be generated using a QR code generator at one of many online sites. Companies and individuals can use QR code to display website, video, text or add a vCard contact to the user's smart phone. Users can also generate and print their own QR codes utilizing QR code generators. A QR Code works by simply scanning the code with a mobile device that is equipped with a camera and QR Code reader application. QR reader or scanner application recognizes the code mechanically and gives you the option of opening it in a browser or sharing it via e-mail or SMS.
Dynamic QR Codes are particularly versatile. Using dynamic QR codes, you can update the embedded information in the code without changing the code itself. They are particularly useful when you may want to change the link or your phone number in your already published QR code. QR Codes have become very popular to attract people to their personal website, blog, articles, twitter page or social media sites. They can be printed on your company cards, greeting cards, occasion announcements, posters, billboards, and so much more.
Advertisers have found them to be particularly beneficial in tracking scan of QR code to show relevant details about their product or offer to the user on their mobile phone.
