American Express (AXP -0.5%) says it's buying e-payment startup Revolution Money for about $300M. Revolution's PIN-activated credit cards cost merchants a fraction of the typical acceptance cost, and offer free online money transfers, a threat to eBay's (EBAY) PayPal. "While Revolution Money is a young and relatively small company, we believe it has big potential," AXP says.
