What are QR codes?
Quick response (QR) codes 
are sophisticated barcodes that can be used to quickly and easily link to information on mobile devices, such as smartphones. These codes, once scanned, can direct you to a Web site, provide you with contact information, download an MP3 file, or dial a telephone number, among others.
How do I use QR codes?
To “read” or scan QR codes, your device must be equipped with a camera and a QR reader. Some smartphones come equipped with QR reader software, but others require it to be downloaded. To download the software, depending on your device, you can you can search the iPhone App Store, the Android Market, or browse Mobile-Barcodes.com.
Where will you see QR codes in Falk Library?
