3. Queen Elizabeth II
Yes, you heard it right. Even the Queen needs a credit card to do her shopping. Queen Elizabeth II uses a credit card, known as the Coutts & Co.’s World Card. This is one of the most exclusive credit cards, especially made for the rich folks. Leaving behind the American Express Black Card, the Coutts World Card is offered by the Royal Bank of Scotland. It has just about a hundred invitations for only purple card customers, among whom one is Queen Elizabeth II.
