It is sooooo easy to read a qr code. You just need a device with a camera and a code reader app. Open the app, it will scan the code using your camera and ask if you would like to open the website, contact, video or anything you've made the code connect to.

Then you would have parents download a QR Code Reader in advance. I like I-nigma,

Dear Parents, please download a QR code reader to your smartphone before Open House so that you can see some of the awesome digital work your kiddo has done. I've included a link to a FREE one that works on all platforms:
I-nigma is a QR code reader, for all platforms including iOS, Windows and Android phones.
