BofA turned the common consumer behavior of saving change in a jar at home into an innovative savings account service called “Keep the Change.” Consumers who use their debit cards to make purchases can now choose to have the total rounded up to the nearest dollar and the difference deposited in their savings accounts. The success of the program lay in the instinctive desire for people to put money aside in a painless way and the program’s natural integration with existing consumer behavior."
