It works, really. – Blippar - The AR browser Review

Cracker Jack fans: in order to get this app to work with the sticker prize, you have to go into settings (upper left-hand side) and turn off explore mode. Then, you stick the sticker in the middle of an 8 1/2 x 11 sheet of white paper so the app can’t see anything else. Scan the sticker for the download to begin. It’s actually pretty fun!
