U.S. credit cards are safe for customers because U.S. banks will cover most losses.

American credit cards are not safe. Where do you think the hundreds of thousands of black cards circulating on the Internet around the world come from? It's just that the overall moral standard of American society is relatively high (the most evil villains are all on Wall Street), and it can still maintain a very healthy state despite being full of loopholes. In the same way, the environmental sanitation in Chinese cities is pretty good, right? If you replace all Chinese people with Indians, the number of people defecating in the open will immediately increase by 10,000 times. The credit card does not require a password, just sign and go. This is a method based on presupposing every customer to be a good person, but once you show a little abnormality, everyone will be attacked.

In China, the opposite is true. There is nothing unsafe. It is just that part of the cost of ensuring security is passed on to users.
