As of 2015, Emerald Card is a prepaid MasterCard through the financial services website H&R Block, according to the company's website. Customers load tax refunds, paychecks and other direct deposits to the card and use it anywhere MasterCard is accepted. Customers are able to get cash out of ATMs and add others to the account so that they have separate Emerald Cards that pull from the same account balance.
