Answer: MasterCard Worldwide
MasterCard Worldwide is an American multinational corporation with its headquarters in the MasterCard International Global Headquarters in Harrison, New York, United States. Throughout the world, its principal business is to process payments between the banks of merchants and the banks of purchasers that use its "MasterCard" brand debit and credit cards to make purchases. MasterCard Worldwide has been a publicly traded company since 2006. Prior to its initial public offering, MasterCard Worldwide was a membership organization owned by the 25,000+ financial institutions that issue its card.
MasterCard, originally known as MasterCharge, was created by several California banks as a competitor to the BankAmericard issued by Bank of America, which later became the Visa credit card issued by Visa Inc. The original banks behind MasterCharge were United California Bank (later First Interstate Bank and subsequently merged into Wells Fargo Bank), Wells Fargo, Crocker National Bank (also subsequently merged into Wells Fargo), and the Bank of California (subsequently merged into the Union Bank of California).
