New this year is QR codes on game code posters, so if you have the right app you can snap photos of game codes and redeem them quickly. Let me see if I can't rig up something here to demonstrate that.
QR codes on Code Signs! If you have a smartphone, get a QR code reader, because we've actually found something QR codes are good for! You can still type in the codes too, it's just a shortcut.
Also new this year is that several members of library staff have their own game codes, which they will happily give you upon request (or better yet they'll volunteer that they have them.) I've done 2 at 500 points each so far!
