Via PlayFire.com (linked above), Gamercard's have been created to reflect your acquired trophies from the PSN. Currently you have to manually update every trophy to each game you get them from, but there is an auto update feature is being worked on that will be linked to your PSN ID. Good news indeed.
To see what they look like, you can view my current Gamercard linked via my profile page on that site http://www.playfire.com/l33t_killa or check it out pictured below.
You can also update the "Level" that your currently at on the trophy scale. For example, I'm half way through Level 2 as you can see in my Gamercard.
