How to Scan QR Codes
Using any smart phone, iPod, iPad, etc., search the word “scan”
in the app store of the device. Several free options should be
available. I prefer the app called Scan. To read the QR code,
just line up the corners of the scanner with its edges.
How to Make QR Codes
There are many free sites to create QR codes on the internet
that I have not yet explored. One I do like and use often in my
classroom is qurify.com. At that site, you type in your message
and click “Qurify.” From there you can either add to the print
queue and then print or download as a png or jpg to open up
in an electronic file.
