STUDENT CARD: Green Dot Corp. is partnering with student lender Sallie Mae to market a prepaid card to students who do not have a bank account. Under the arrangement, any money left over from a Sallie Mae-issued student loan will be loaded onto the Monrovia’s company’s My Flex prepaid MasterCard that students can use to pay for books and some other expenses. The partnership may help Green Dot counter a loss in sales of its cards at major retailers where it is losing its exclusivity arrangements.
