It is not just back-to-school time for college students-PNC Financial Services Group is going back to school as well.

In recent weeks, the Pittsburgh company has forged deals with three universities and it is eyeing others within its markets as more contracts for campus ATMs, branches and other banking services are put out for bid. Following its March acquisition of RBC Bank USA, PNC is especially looking for deals in the Southeast, according to Nick Certo, senior vice president and manager of university and workplace banking for the $292 billion-asset PNC Bank.

At least two dozen schools have "told us that they are going to be approaching the market in the next six months, looking for partners," Certo says.

PNC has focused on a variety of partnerships with colleges and universities since the mid-1990s and, as it has grown, so too has its campus presence. It now has more than 200 university banking relationships within its 15-state footprint.

Like many banks, PNC is aiming to boost visibility on college campuses as a way to attract young consumers who many not have a dime to their names now but have high earnings potential down the road. The relationship PNC has with each school can vary and is sometimes an evolutionary process, Certo says. At first the bank may only talk to the school's students and employees about checking or savings accounts and over time may expand upon that initial relationship to include other services.

In its agreement with Georgetown University announced earlier this month, students and university employees will be able to link their campus cards to PNC Bank accounts. They can then use their campus card like a debit card.

In other deals announced in September, PNC said it would install a dozen ATMs in the student center and athletic facilities at Auburn University in Alabama and that it would open an electronic branch, which has customer service employees rather than tellers, at the University of Maryland, Baltimore County.

PNC's hope, of course, is to retain these college students as customers once they graduate. Certo says that PNC has been "successful" in this regard but declined to give specifics.

PNC isn't the only bank that sees potential in college students. Other banks, including Huntington Bancshares (HBAN) and Webster Financial (WBS), have recently struck deals with major universities as they seek to boost market share.

This isn't surprising considering the earnings potential for college graduates over their lifetimes and the pressure on banks to add customers and grow top-line revenues, says Scott Siefers, a managing director at Sandler O'Neill & Partners. Aside from traditional banking products, college graduates may also be are candidates for asset management products in the future, Siefers says.

"We are at a point in the industry where profitability is not easy to grow," Siefers says. "To the extent that you can attract and retain customers, including the young who could be with you over a long period of time, is good. Hopefully you can sell them additional products over time."

Huntington announced an exclusive 15-year deal with Ohio State University earlier this year that will jettison some of its main rivals, including Fifth Third Bancorp and U.S. Bancorp from the campus when current contracts run out. Webster Bank said in July that it had reached a wide-ranging sponsorship deal with the University of Connecticut that includes ATMs at the school's sporting venues.
