More than half of U.S. consumers have access to mobile banking software from ClairMail Inc., the Novato, Calif., vendor said Wednesday.

The privately held company said that revenue in the third quarter increased 200% over the same period last year, though it did not provide specific numbers.

ClairMail said that more than 45 banks, including six of the top 10, are offering its software to their customers. Those clients have more than 161 million banking customers, or about 53% of the population, it said.
