QR Code in shopping cart handle
Are people using QR codes frequently here in the states or elsewhere?<p>To me I see them everywhere, but curiously most phones don't have them built into their camera apps (iPhone's camera doesn't have built in scanner) or have some quick an easy way to scan QR codes.<p>Rather you have to download an app and then later find that app, then fidget a bit too much to get the app to read the code.<p>Not the greatest user experience and I have found it frustrating!<p>What advances have been made and or are being made to make QR code scanning quick and painless?
