American Express (AXP) expands its push into the Social Network, going after the FarmVille crowd by rolling out a line of co-branded prepaid cards with Zynga. Users won't need a credit check, but will need to sign up for a Serve account, which can be funded from existing bank accounts, or debit/credit cards.
