OK, first of all, the simplest point is that behind all credit cards, there will be terms and conditions, such as, "obey the credit card usage policy" and other nonsense, haha, when you see these words, it must be a credit card. .

Secondly, the numbers on the surface of all credit cards are protruding. Of course, except for the credit cards cooperated by China Merchants Bank and PepsiCo, the card number is printed on it.

In addition, credit cards support authorization functions, and the authorization functions are mainly performed through third-party platforms. Commonly seen ones are VISA, MASTER, AE, JCB, DINNER, etc. Therefore, the card must have You need these signs.

Generally speaking, credit card numbers are usually 16 or 15 digits, and the numbers they start with are not the ones that start with ordinary debit cards, such as: 95566 95599, etc., for example, ICBC’s is 3702, etc. .

It seems to be a cooperation with VISA. HOHO, this is You must remember that when using a card, you can only authorize, complete the authorization, go offline, etc. on UnionPay POS machines. If you do it on other machines, the authorization form or completion form that comes out will have no practical meaning, it is just a card form. That’s all.
