What you should ask is how to distinguish debit cards from credit cards. In fact, credit cards are easy to recognize. 1. It should be obvious from the front of the card. The card number and date in the middle of the card and the English or pinyin name under the code are all credit cards such as "Mr. XXX". 2. Look at the back of the card carefully. There will be small words under the signature, such as "Use is subject to XXXX credit card regulations", which is the credit card. In addition, some credit cards will have small characters above the magnetic stripe on the back, such as "Chinese banknote credit card".
