Washington Trust Bank in Spokane is offering mobile banking services to its customers through text, mobile Web and dedicated applications using mFoundry Inc.'s software.

The vendor said Wednesday that the $4 billion-asset bank is offering an app for users of Apple Inc.'s iPhone and iPod Touch devices, some of Research In Motion Ltd.'s BlackBerry smartphones, as well as devices running on Google Inc.'s Android operating system.

Customers can use the apps to check balances, make transfers, locate automated teller machines and pay bills.

WTB Mobile is available to download in Apple's App Store and Google's Android Market.

Customers can also gain access to Washington Trust's enhanced mobile website and use text commands to receive account balances and transaction histories and make transfers.

"As we set our mobile strategy, our primary goal was to offer a mobile solution that served our customers regardless of the phone they have while still providing deep functionality," Jim Brockett, the chief information officer of Washington Trust, said in a press release.

The bank's customers must be users of its online banking service to enroll in mobile banking.

mFoundry has about 260 customers using its mobile banking technology, Drew Sievers, the Larkspur, Calif., company's chief executive, said in an e-mail.

Sievers said mFoundry started the year with about 60 financial institution clients.
