China Post's door-to-door application for a credit card is fake, and swiping the card 299 is fraud. According to relevant information, China Post has not provided door-to-door credit card service. When handling a credit card, you need to provide a lot of personal information to the cardholder, even a copy of your ID card. You must first verify the identity of the card handler. Each card manager has his own work number. Before submitting personal data, you should call the customer service phone of the issuing bank to verify the identity information of the card clerk, and then submit the data after confirmation, so as to avoid being defrauded by other fraudsters.
