Working with 2d Codes
How 2d Codes Work 1. A 2d code is created with a 2d code generator and incorporated into some print collateral. 2. A smart phone with a QR reader app is used to scan (take a picture) of the 2d code. 3. The 2d code is “captured” on the smart phone and decoded by the app. 4. After the 2d code is decoded, the URL is opened in the user’s browser.
Generating a 2d Code
Finding a 2d code generator is easy―just search Google for something like 2d code generator or QR code generator, and you’ll find a plethora of options. The generators are typically free (some 2d code website companies offer additional, paid services such as code scan tracking and analysis). One of the most useful and user-friendly 2d code generator sites is Kerem Erkan. However, the choices are vast and most of the generators work the same; some are just more elaborate than others. Once the code is generated (depending on the generator) you either save it to your computer or copy and paste.
Scanning a 2d Code
Many smart phones are shipping with QR readers pre-installed these days. If your phone does not have one (or the right one) you will need to download an app. Search the Market or App store on your smart phone for something like QR reader, or the specific name of the reader, if you know it. Some popular readers are BeeTagg, i-nigma, ScanLife and NeoReader.
When you come across a 2d code that you want to scan, launch the app and hover over it with your smart phone’s camera. Typically, the code is read by the camera auto focusing; once the code comes into focus, the embedded code will be resolved and the action (such as launching an URL) will be executed.
