Speed, simplicity, ubiquity.

Jonathan Larsen, Citibank's head of consumer banking for Asia Pacific, spoke with the Wall Street Journal's "Managing in Asia" columnist about investments in technology supporting the company's expansion of retail banking the region. In the piece, "Pushing high-tech in growing Asia market," he discussed successful efforts to bring a full range of banking services to mobile devices such as smartphones and tablets; the launch of "transit branches" on commuter routes in Sinagpore, Hong Kong, Shanghai and soon Tokyo; and the rollout of state-of-the-art interactive technology across the rapidly growing Asian retail branch network.

"Speed, simplicity and ubiquity are guiding our use of technology," Larsen said.
