Green Dot Corporation is an issuer of prepaid MasterCard and Visa cards in the United States. These products are available at more than 60,000 retail stores, including CVS, Rite Aid, Walgreens, RadioShack, and Dollar Tree; as well as with discounted offerings at Meijer and Walmart. Green Dot also transfers individuals' direct deposit funds (such as Social Security payments) from the US government to personal bank accounts. The cards may be used like normal debit or credit cards, but they are not backed by a checking account or line of credit. Purchases are deducted from the balance stored on the card. The user can add more money to the card by paying cash at a retail stores point of sale, or in certain cases from their paycheck. Green Dot is headquartered in Pasadena, California, and it was formerly known as Next Estate Communications. The company provides co-branded card programs to Walmart, Boost Mobile, AT&T and Citibank. In 2007, Green Dot raised $20M in funding, including Sequoia Capital as an investor. In 2008, Green Dot ceased to offer prepaid Discover cards.
