Over the summer Bungie have done some promotional trading card things to hand out at the games conferences
There were original 5 but another three have appeared over the last week.
You enter these at the same place you put your beta code.
Nobody knows what exactly they are for but they will be unlocking something in the game when it releases.
Interesting! Even if it's just weapon skins or something of that nature it's still a cool hidden promo.
