QR Codes / QR Code Generator
QR codes are an excellent rapid way of accessing material, typically a website. With a QR code created and displayed, a person usually uses a smartphone or an iPad with any QR reader app (nearly all are free) to "scan" the code and get access to the material. However, what if you don't have 1:1 smartphones or iPads? And with something like Empower where you can easily just post a link, why bother with a QR code?
To the latter, an argument could be made for the positive kinesthetic nature of using QR codes (walk around and scan...); how QR codes could be part of "self-service" stations, especially for younger learners; how QR codes can be more than just links (for example, they could be a short message of text). To the former, a website called QR Code Generator allows you to scan via your browser; no program needs to be installed. Just go to the link, give permission to your camera the first time you visit, and you can use your laptop as a QR code scanner! At the same site, you can also create static and dynamic QR codes to save as images or print.
