This presentation covers information about QR codes and ideas for using them in drawings and mapping
QR codes have code embedded into their design. This slide shows the areas of the graphic that carry the necessary code. Although it’s said that up to 30% of the code can be damaged and still function, it’s a good idea to try to keep these areas free of any damage or obstruction.
The background of the code can be colored in either one or multiple colors. The important thing to remember is to keep a contrast between the marks holding the code and the background.
Pictures and graphics can even be added to enhance the image as long as the necessary areas remain free of an obstruction.
This is an example of using QR Codes on a cover sheet of a set of plans. One points to the IDOT specifications and the other to the JULIE number.
This is an example of using a QR Code on a detail. This particular QR Code points to a 3D rendering of a lift station. The 3D image on the related website can be tilted and moved around for better views.
This is an example of other images that could be activated by QR codes on plans. This gives the viewer the opportunity to see the design in better detail from all angles or even the operation of a design element.
QR Codes are often used to physically tag something out in the field so that information about an asset can be quickly collected.

What are QR Codes? A QR code (abbreviated from Quick Response code) is a type of matrix barcode (or two- dimensional code) first designed for the automotive industry. definition from Wikipedia
What are they used for? •Access a website •Call a specific phone number •Generate and give you the option to send a specific text message •Play a video from a website •Play an audio file from a website •Send an email •Send contact info •Generate a Tweet on Twitter

Ideas for implementation Put QR Codes on Plans to link to •Specifications •One-call locate services •Videos •Details •Audio
This QR Code links to an online 3D rendering of a station that can be manipulated by tilting and zooming.ftp://ftp2.bentley.com/dist/collateral/Web/Gallery/ch2mhill_pump_station_3.pdf Note: the 3D image and CAD drawing are not related and only used for demonstration purposes
QR Codes on inlets could not only link toinformation like coordinates and elevations. Butthey could also link to information about wherethe system drains and other stormwaterinformation in general.
QR Codes Enhance Community Education QR codes are used at historic sites and other areas as a method of linking to additional information. Could these be used as part of an educational game allowing citizens to find and “tag” objects in the community as they learn more about public works or community history?
Security Concerns There are concerns that QR Codes could be used to trick people to visit websites that contain malicious code. Be sure of the site you are visiting, and never log into or share personal information on a site you have arrived at using a QR Code.
Making QR Codes There are many free sites where you can generate a QR Code. Google: http://goo.gl Kaywa: http://qrcode.kaywa.com/ QR Stuff: http://www.qrstuff.com/ Microsoft: http://tag.microsoft.com/home.aspx
Reading QR Codes You need some type of camera device to read a QR Code. Most QR Codes are read with smart phones with applications like the following: Neo Reader: http://www.neoreader.com/ Scan Life: http://www.scanlife.com/new/
