QR Codes are making a comeback - @jcasatodd | iPads, MakerEd and More  in Education | Scoop.it
You either love them or hate them. Some educators feel like using QR codes are unnecessary; why not just give kids a shortened URL? Last year, I asked my high school students what they thought about QR codes as a way to access information in my Library Learning Commons. Responses varied slightly, but the general consensus was:

“Nah. We don’t use them.”

“They’re lame, Sorry Miss.”

Then came the iOS 11 update about a month ago. This update turned the iphone camera into a QR code scanner.
