In addition, in the fraudulent short messages sent by impersonating a bank through a pseudo base station, whether the amount is adjusted, the points are exchanged for cash, or the card is handled, the address of the phishing website is generally included. After entering the phishing website, you will need to enter the card number, expiration date, security code (the last three digits of the signature column on the back of the credit card), dynamic verification code, etc., especially this security code and dynamic verification code, which are the key to completing the transaction. Here, the bank sends a short message with dynamic verification code. Be sure to read it carefully. The bank will clearly write down the purpose of the transaction, whether it involves the amount of specific transactions (purpose: consumption/pre-authorization is generally written). If it involves the specific amount, it must be drawn from the card. The landlord must not hold the illusion that he can receive the money, and he must not disclose it decisively. With 12 eyes open, it is very likely that you have entered the trap of a liar. Therefore, you must stop typing and come back to the bank customer service hotline for consultation (the back of the card is the regular service hotline).
