I am now seeing QR Codes more and more in what I would call the mainstream. My most recent observation was at my local railway station (managed by First Great Western) where I was checking the timetable and noticed the QR Code in the corner.
Looking at it in more detail, I just had to scan it in, well one does these kinds of things…
I use Optiscan on the iPhone as I have found it to be very reliable and certainly on the 3GS was the best option I found. The reason I like Optiscan is that it works nearly every time.
Of course all a QR Code is, is a shortened URL and no matter how easy it is to scan in with the phone, the key, the end result is how does the final web page look on your mobile device.
I wasn’t that impressed with the landing page as I had to click a link to actually get the timetable.
I am pretty sure that FGW have done that because the timetables change, but even if that was the case, they would also need to reprint the printed version so could then print a new QR Code. Another reason might be to gather stats from the landing page. The actual digital timetable was in PDF format and was usable on the iPhone.
However given the choice I think I would probably use the Train Times App (also available on Android) which also gives live travel information so you know if your train has been cancelled. The problem with a PDF timetable is that it won’t account for live changes to the timetable, you could certainly have a QR code on a printed timetable linking to a live timetable, and I think FGW should have done that.
