“Fintech,” or financial technology," is a term that seems to be on everyone's lips these days, from bankers to global finance ministers. Dramatic advances in computing power, speed, interoperability, and nearly instantaneous internet communication are changing the ways banks, brokers, and other financial institutions relate to their customers, investors, regulators, and each other.
