T-Mobile's fee-free Money banking service, officially launched earlier this month, relies on the Minneapolis fintech firm ClickSwitch Holdings Inc. to attract customers from other banks.
The relationship is a turning point for ClickSwitch, which created software to simplify the process of moving a person's direct-deposit and bill-payment information from one bank to another.
The firm in the past two years has signed up more than 300 banks to incorporate its technology into their online services and mobile apps. But most of those firms are small and haven't launched a national marketing campaign in search of customers the way T-Mobile just did for T-Mobile Money.
"We are forecasting T-Mobile to be one of our largest clients," Cale Johnston, chief executive of ClickSwitch, said Monday. "Shortly after their launch we are already experiencing tremendous volume."
He added that T-Mobile is "raising the standard for digital banking across the industry."
A T-Mobile spokesman said via e-mail that it considered various technologies to reduce what the company viewed as customers' "pain points" in banking.
"Direct deposits are one of those pain points," T-Mobile said in a statement. "People have typically had to fill out forms, give them to HR and then wait to have the changes happen. ClickSwitch makes changing direct deposits and allocations between accounts super simple."
With the launch of T-Mobile Money, the nation's No. 3 provider of wireless service is one of the first major tech brands to jump into personal finance. Apple Inc. announced in March that it would offer a credit card later this year.
