So, it looks like Destiny's creators are doing something for people that want to play the game.  

At various events throughout 2013, Bungie dispersed trading cards to very select international audiences. The cards had detailed descriptions and concept art for various locations, characters and weapons, as well as codes that can be redeemed on Bungie.net.

The rewards for each card will be small, in game content, though they won't say what the content is. 

To redeem the codes, just go to Bungie.net, log in to your account, and put whatever codes in you want.
