Mobile banking by app is getting big in Texas, a new survey shows.

Thirty-three percent of respondents now use mobile apps on a smartphone or tablet, up from 20% two years ago and 7% in 2009, according to SWACHA–The Electronic Payments Resource, a Dallas-based not-for-profit payment association with about 1,100 financial institution and other clients across the Southwest.

SWACHA released the results of its 2013 survey on Thursday at its inaugural Executive Leadership Payments Summit in Dallas. The online survey of 601 Texas residents, completed only by those who identified themselves as responsible for paying household bills, was conducted in April 2013 by Decision Analyst and carries a confidence interval of 95% and a margin of error of plus or minus 4 percentage points, SWACHA said.

SWACHA said 20% of those surveyed use a mobile banking application daily while 45% do at least once a week.

 Depositing checks by mobile device also grew sharply, up to 46% of respondents doing so now compared with 16% in 2011, SWACHA said its third survey since 2009 showed.

 “This year's results show many significant trends in this rapidly changing environment that we will continue to monitor, such as remote deposit capture, which is not only changing the way people interact with technology, but it's also changing the way people interact with their banks, and it's an adjustment the industry is welcoming,” said SWACHA CEO Dennis Simmons.
