PNC Financial Services Group Inc. is rolling out mobile check capture to its main customer base after a successful initial rollout with customers of its online-centric Virtual Wallet account.

PNC formally announced the expansion Tuesday, though the update to its iPhone app went live last week.

The technology allows customers to deposit endorsed checks by photographing them with a mobile phone's camera.

PNC said it introduced this feature to its app to respond to changes in customers' banking habits.

"There has been unprecedented change in consumer preferences and customers' relationship with their money," Tom Kunz, PNC's senior vice president and director of e-business and payments, said in a press release. "Mobile deposit is another way that PNC makes it easier for customers to achieve their financial goals."

The app, developed by mFoundry Inc., also works on Apple Inc.'s iPod Touch and iPad 2 devices, which have built-in cameras.

PNC said that depositing a check with its app takes about 90 seconds and that funds from checks deposited before 8 p.m. are typically made available the next business day.

The Pittsburgh banking company first offered remote deposit capture for business customers in 2006.

Its Virtual Wallet account, launched in 2008, was designed for consumers who conduct most of their banking interactions online and thus have less reliance on branches. Though it was initially pitched at younger consumers, Virtual Wallet was expanded recently to provide options more appropriate for an older demographic.
