Facebook launches API and bill-sharing service
Using FaceBank is a bit confusing. The service is designed around the concept of lending to and "mooching" from friends organized in groups called piggy banks. A bank is a group of people you define by selecting from a list of your Facebook friends. FaceBank keeps track of all the loans within a piggy bank and will minimize the number of transactions required for the entire group to settle up. For example, if I owe Noah $20, and he owes Matt $20, FaceBank will instruct me to pay Matt $20 and mark both debts as settled. Entering a loan or a mooch consists of selecting the person you owe or owes you from a list and entering the dollar amount with an optional description of the credit or debit.
Unfortunately, there's no way to enter a large bill and split it between multiple people; instead shared costs must be entered as a loan, forcing you to do the division to determine how much each person owes. There's also no way to select more than one friend at a time when entering a loan or mooch, nor is there a mechanism to limit the friend list to the particular piggy bank you're in at the moment. Another obvious missing feature is the ability to turn a pre-existing Facebook group into a piggy bank.
Though it's undoubtedly rough around the edges, with a bit of development--from Facebook themselves or a third party developer with the API--it could dominate the college micro-loan and bill-sharing market.
