Bank card is a very important tool in daily life, and many applications need to be bound. Bank cards can be copied at the printing place, which is generally safe, but if users are really worried, they can go to the bank to copy.
When handling business, you can ask the staff to make copies for you. Usually, bank copying is free, and the specific conditions are subject to the specific regulations of bank outlets.
Others only know the bank card number, which is generally not dangerous. But if others know the payment password and SMS verification code corresponding to the bank card number, or the credit card number and the corresponding CVV2 code, it will be more dangerous. They can successfully pass the payment security verification, transfer the balance on the card or use the bank card for consumption.
