Facebook is targeting a multibillion-dollar business as it tries to regain the confidence of investors worried about the company's money-making potential. A new gift card works with all retailers and can have multiple balances – say for bread sticks at Olive Garden or a box of diapers at Target – and balances can be monitored on Facebook mobile apps. While founder Mark Zuckerberg warns that his company's gifts and retail business won't trickle revenue for some time, investors are pinning their hopes on Facebook making a major play in commerce, the Los Angeles Times reports.
