Bingo & QR code (how can I build a scavenger hunt game using bar codes)

When students get bingo lattice, they can play bingo game.
um..just like there is a 4*4 size bingo game, from number 1 to 16
when I choose NO.1 lattice, i'll see a question..
Question: which plant has 3 kinds color flower?
then i go to find the true plant and scan the QR code.
I can get NO.1 lattice, and so on..
The other rule is as same as bingo game.

I am new here. do you have any sample like that?
I would appreciate it if you could take a moment to explain that to me.
Thanks for your reply.
