Scan, Link, and Learn: QR Codes

QR Shrub Sign Example

Example of a Purdue Arboretum Explorer QR Sign

Throughout the Purdue West Lafayette Campus you will find QR codes (Quick Response Codes) displayed on plant signage.  These QR codes will direct you to the Purdue Arboretum Explorer website where you can learn more about the plant or landscape feature.

QR codes can be used in Google Android and Apple iOS devices (iPhone/iPod/iPad), as well as Microsoft’s Windows Phone operating system, Google Goggles, 3rd party barcode scanners, and the Nintendo 3DS.

General QR Code Scanning Tips
  • When scanning, hold the phone steady, so the image stays in focus. Do this for other things you scan, too.
  • Make sure the QR Code appears completely in the viewfinder on your phone.
