How to view an existing QR code at http://go.unl.edu:
Standard size of QR Code:
"The minimum dimensions of a QR code depend upon the resolving power of the cameras that are used to scan the code. According to a Kaywa white paper, it is recommended to use a minimum size of 32 �?�?? 32 mm or 1.25 �?�?? 1.25 inches, excluding quiet zone, for QR codes that contain a URL. This guarantees that all camera phones on the market can properly read the bar code. Changing the size to a width and height of 26 �?�?? 26 mm or roughly 1 square inch still covers 90% of the phones on the market. The latest camera models, which have improved macro capabilities, can however already deal with QR codes that are less than 10 mm (0.4â�?�³) wide and high." from
