Most of us know the iconic line from the song Take Me Out to the Ballgame "Buy me some peanuts and Cracker Jack..." (best performed by Harry Caray) and likely we've all had the box of carmel-coated popcorn with peanuts and a little prize tucked inside.

Not sure when packaging changed from a box to a bag, but now the 'prize' inside is a code, not a fake tattoo, sticker or one of the 'good' prizes (pictured above Harry) from the 1970s. Now, the QR code prize can be scanned by a phone, a special app is downloaded, which gives access to a video game with a baseball theme.
