Many people have a question, China's mobile payment is very developed, why does the United States still like to use credit cards so much? What is the reason for this difference? If I go to the United States, how do I use credit cards?

many argue that this will not work, that credit card marketing in society will always affect college students, and that card issuers will always find ways to get around the rules.

Cardholders must know how to protect themselves against different types of fraud.
