Bank of communications credit card, the envelope was opened when it was received, and it was given to me by the postman himself. The postman said he didn't open it, but it was already open when he received it. Foreign payment really doesn't need a password, as long as the front and back photos are enough. I used to do visa-related things abroad. I need to pay for the invitation first, that is, I sent the front and back photos directly. A few days later, direct news came and how much was deducted. I don't need a password at home. I've experienced it myself. Besides, the new card should be stuck on paper, right? Is it possible to show the seven digits on the back? If it is, it must not be used again. There should be no charge for selling cards directly.
