Shoe, search your apps for a scanner. If you have an android then you should have a "Google Play" icon that takes you to the app store. Then search for "QR Scanner" and I bet you'll find it. Once you get it, you'll be looking for those qr codes everywhere and scanning them all. It's actually a lot of fun for a while.
I like your idea of an automatic post to the Plant ID forum. It's something that I'm not ready for yet but I think it would be great to put on my wishlist for "some day".
