This should give you foundation to look at some of the apps that you’ll needout for

QR Reader There are two creators that I like using: I like it because you can watch it actually make the QR.
Google Url Shortner – What I like about this site, once you establish an account, google will keep a listing of your QRs.  Why is this important?  It will record the number of times your site has been contacted (hit).  A nice feature to show if your students are actively using the site.
QR stuff - This one makes it easy to download and change colors.
This one goes into good detail.  Here is the web site qrpath
Azonmobile - This one allows you not only to make a qr but gives you a lot of control over it.
