Millennials would rather use their mobile phone than do their banking at a traditional branch by an overwhelming margin, according to a new survey from Chime, a mobile banking company. The research showed 88% of Millennials would rather use a bank app or website than perform a banking service at a branch.

The country’s largest living generation, with nearly 80 million people between the ages of 15 and 34, are not enchanted with the services offered by their banks. Only 31% of Millennials would recommend their bank to a friend. Furthermore, 37% tell others not to use their bank.

This dissatisfaction probably stems from the fact that they are not getting the services that are important to them. Nearly two-thirds of those surveyed would like to receive mobile notifications about deposits and transactions, but almost 80% are not getting them.

Millennials also want to be rewarded for their business. 80% of those surveyed also said it was important for their bank to offer them a rewards program, but 68% reported that the do not have one. Specifically, Millennials want a debit card with rewards, as this generation would much rather use their debit cards than a credit card. In fact, 67% prefer using their debit cards.

Millennials are likely avoiding credit cards as they are increasingly dealing with student debt. Nearly 40% of those surveyed had student loans. The other top sources of debt were credit cards (34%) and auto loans (32%).

Chime surveyed 1,262 people between the ages of 21 and 35. They used a SurveyMonkey audience to determine what these millennials look for in a bank.
