QR codes (Quick Response Codes) are a fast way to share information, pull up websites, and so much more.
If you have a quote, a scripture, or something to share with your class members you can make a QR code and allow your class to scan it with the camera on the cell phone. Rather than have them try to find the scripture verse, for example, you can create a QR code so your class can immediately open it up.
