Well, yesterday I was reading the Wine Spectator (yes, one of my favorite 'hobbies' for years - )
A short article on QR Codes (Quick Response Codes) discussed the recent introduction of these small square matrix pictures (like a different bar code) - sample below - on wine bottles which can be scanned and then propel you to a web site w/ information on the wine in the bottle and/or the winery - BOY, there is a lot of potential in that purpose but so many more possibilities.
These were created by Toyota way back in 1994 to track cars during manufacturing - more in a Wiki article HERE!
Well, I checked the Apple App store and put the 'free' app QR scanner by Engage on my iPad - not sure if this is a good one (ratings varied a lot) and others may be better (advice appreciated?) - but was able to scan in a 'code' from the magazine which took me to the Wine Spectator website immediately - kind of neat; well I had a 'free' calendar from Williamsburg, VA w/ a similar code - took about 5X w/ that app to bring up a cool site for the colonial preservation site; finally, this morning, our local paper arrived - has had these codes for a while, so gave it a try and took me to a web site w/ an updated calendar of events happening in my local city!
Tried to do some searching on the forum but could not find much on this technology or iPad applications (may have missed a thread or two - sorry, if so) - but for those that have been using these codes, there seems to be a GREAT future - just a simple camera scan from the back of the iPad - again, would appreciate comments from those using this or other programs, which one(s) is the best - not sure if the apps that work on the iPhone and/or the iPad may be BETTER w/ the iPhone in scanning in these codes? The reason for consideration is the marked resolution differences between the cameras on these two Apple devices - does it make a difference?
Thanks all for any input - although I've know about this technology for years, this is really my first trial w/ these interesting codes - a LOT of potential -
