You use the small card to pick up your pre-order, make sure you redeem or write down your codes from the big card in case they want to try to take that one back for some reason. I had to visit 2 Walmarts to get my pre-order, the first one (more convenient to get to) they were just on Walmart's website trying to pre-order me a PS3 system, when I specifically asked for the game, the second one they just had the pre-order cards sitting out among the games on the racks.

Side note: If the cards are left out unprotected, what's to stop someone from scratching the codes in the store and redeeming them?
The codes are not active until scanned by the register. That goes for all cards of the sort. including xbox points and playstation cards.
