Many banks in the United States decided to follow Amazon's example to provide benefits for users, so American Express can use Amazon as its credit card, and Amazon and American Express also launched a new joint credit card.

Amazon said in a statement that cardholders with Amazon Prime membership will be able to choose between a 90-day interest-free loan and a 5% Amazon shopping refund. In addition, this free metal card can also enjoy a 2% discount on restaurants, gas stations and mobile phone services in the United States.
