摘要：As the percentage of using smartphones in campuses increases, the use of two-dimensional barcodes becomes very useful, so do the applications associated with them.

It can decrease the partial attention in the laboratory by connecting students electronically using their smartphones to a video, a blog, a data sheet that visualize the experiments.
