What are QR Codes?

Many mobile phones, including Android based phones, offer QR Code compatibility through the use of "bar code or QR code scanner" applications. You can use these types of applications to scan these QR codes on Android devices to take you directly to the Android market where you can learn more about applications available from CALECO Ventures.
A QR Code is a specific matrix barcode (or two-dimensional code), readable by dedicated QR barcode readers and camera phones. The code consists of black modules arranged in a square pattern on a white background. The information encoded can be text, URL or other data. Wikipedia provides more detail about QR Codes in general.
