what is a world mastercard
In general, World MasterCard and Visa Signature cards will both offer you substantial savings and exclusive opportunities. By using one of these two cards, you will have access to a lot more. However, these cards offer very similar rewards and it can be confusing to compare.
Mastercard, originally known as Interbank/Master Charge, 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. From 1966 to 1979, Mastercard was called Interbank and Master Charge.
