Hi
OOOps, my bad. This weekly lesson went out with the wrong title. "How to choose a smartphone case" when it should have read, QR codes, how to use them and how to make them. Sorry for the extra email. Here's the real tip about QR codes:
------------------------------------
We are traveling in Australia this week and we won't be doing a live show, but I have an Encore episode I think you should watch!
While visiting the Koala sanctuary (see photos here) I noticed a billboard that had a QR code on it. A QR code is something that looks like the image at right. The instructions said to scan the code to get a map of the park and I saw someone looking at it quizzically and looking around for help - "How do I scan that code?"
Ha! Geeks to the rescue. We showed her how to open her camera on the iPhone, point it at the code, then tap the link that appeared. She was thrilled.
In Episode 146 of our What Does This Button Do show, we show how to make your own QR codes as well as read them. If you already know how to scan, try it on the code above and it will take you to our web page with the show and, if you are a member, you can also read the show notes.
