Homework with QR code

When scanned it takes the child to an instructional YouTube video related to the assignment/lesson. What a nice idea to add an extra information channel for a better understanding of the students.

It is interesting to observe how the QR code has made its progress from the first designs in 1994 for the Japanese automotive industry and spread it’s reach to all the other areas of modern life.

Which other places will the Qr code be placed upon in the future? What were the most interesting places you saw a QR code and did it seem useful to you?
