In China, passwords are basically recognized. You can pay attention to observation. After domestic consumers swipe their cards, they enter the password and print out the receipt, and the clerk asks you to sign it and take it back. She doesn't usually take it. According to international practice, the signature comes first, and the password is basically not recognized. In many countries, credit card readers don't have password keyboards at all. Influenced by China's temper, neighboring countries and Southeast Asian countries began to recognize signatures and passwords, especially UnionPay cards.
