I read through a few hand-outs and online articles, I see people mention a lot about using QR codes to promote their brands or to advertise their products, but not much mention about using it for traveling purposes. Honestly, I myself have never scanned those promotional QR codes. I find it is most interesting and useful to use QR codes when traveling. Today, many airlines offer QR codes for boarding pass, and many airports provide QR scanners as well. I can use airlines' mobile app to check-in and download a QR code as my boarding pass right on my smartphone. I do not need to wait in line at the counter or kiosk at the airports to print out the paper boarding pass. Another thing I find interesting is the use of QR codes at museums or any kind of exhibits. For example, when you walk through an art museum, you can use your smartphone with a QR reader to scan the QR code next to a painting and learn all about the painting, the genre, the artist, his/her contemporaries, etc.
Rather than a coupon or promotion, the QR code as use for traveling is such a convenience tool for travelers. It would make for a much more informative and enjoyable time at the museum. The QR code is a tool that can greatly enhance the consumers' experience, it is not simply a new technology. However, there are still some disadvantages to QR codes. Sometimes it takes longer to be scanned because there are many QR generators and many different kinds of smartphones or QR readers; and not all of them work well together. For example, one time I had to step aside at an airport boarding gate and yield to other people to go first because the airport bar-code reader could not read my QR boarding pass. Also, not every airports is equip with QR readers, so paper boarding pass is still necessary. However, overall, QR codes help our lives by taking us one step closer to a paperless future, and having every conceivable information at the tip of our fingers.
