UNDATED (CNN) -- The nation's biggest banks are rolling out the next generation of ATM's. The latest models include features like video chatting with a live teller and getting change or paying your credit card bill.

Bank of America's new teller assist machines, for example, allow a customer to swipe a debit or credit card, driver's license or photo ID for authentication.

Then a live teller, physically based in Delaware or Florida, pops up on the screen to assist the user. The bank says the machines will be able to perform about 80-percent of the services a traditional teller can.

They'll also be open longer than traditional bank branches.

Analysts say ultimately the banks investing in new ATM technology hope to reduce costs and keep customers coming back.
