Welcome to Linfield College's QR code website. At various points around campus there are barcodes like the one below that are called QR codes. We are currently working to bring awareness to the existence and functionality of QR codes. So, if you see any QR codes scan them with your phone using a QR reader and learn more about Linfield College. Happy Scanning!
What is a QR code: A QR code is a two dimensional barcode that stores information that is downloaded when you scan the code using a mobile-phone. The information could be a text message, a url, or a phone number.
How long have these been around: The QR code has been around for quite a while. It was created in 1994 by Toyota subsidiary Denso-Wave and is very common in parts of east asia. Despite being released in 1994 it has taken a long time for QR codes to catch on due to a competing standard, Data Matrix, which was created in 1989.
Why create QR codes when we have Data Matrix: QR codes were developed due to Data Matrix inability to embed characters such as Kanji into the barcode. The rising popularity of QR codes compared to Data Matrix is mostly due to Japan's growth in technology and their creative use of QR codes. Data Matrix is still used a lot in the U.S. but are sometimes unnoticeable due to their very small size. This small size leads to a disadvantage for Data Matrix in the mobile-market as it is difficult for phone cameras to read such a small code.
If you would like to create your own QR code there are several different sites that will generate QR codes for free. The ones for this project were made with the Kaywa QR Generator.
