QR Codes have been common in Japan for many years and now gaining more exposure in Europe and the United States. The QR Code standard was developed by Denso Wave in Japan, released in 1994 and initially used for tracking parts.

QR Codes contain information in both horizontal and vertical directions compared to a single direction barcode.

The QR Code is defined and published as ISO standard and QR Codes obviously look different to each other depending on the data encoded but the only significant no data variations are the number of elements / dots needed to store the data within.

With most mobile phones or PDAs today a suggestion of Version 4 or lower with QR Code image being 2 cm, roughly 0.85 inches. QR Codes also include Position Alignment Markers, Error Correction data and Calibration of its Orientation.

This allows the QR Code to be scanned if it is upside down, at an angle or on a curved surface.
