China Construction Bank Corp, the nation’s second largest commercial lender by assets, is deepening the transition to an innovative smart bank with comprehensive businesses and diversified services.

The bank has built 12 smart banks and a batch of flagship outlets, offering services through nearly 20,000 simplified smart teller machines and more than 1,000 standardized STMs. Its smart robot customer service launched on the web and mobile phone devices has served more than 1.2 billion clients since 2013, or 2.3 million people per day on average, with the accuracy of replies exceeding 90 percent.

“China Construction Bank keeps improving its innovation system and abilities, especially putting a greater emphasis on business model innovations, in the effort to realize a transition from size-driven to innovation-driven growth,” Bank Chairman Wang Hongzhang said today.

“When technologies and strategies have become the strengths of a commercial bank, size is no longer a problem,” he added.

From 2013 to 2015, CCB made more than 3,600 innovations, 3.5 times the number between 2010 and 2012.
