When lending money, CCB should write down the purpose of the copy of ID card to avoid using it in other places.

It is the most basic thing not to borrow a copy of your ID card and important documents.

Copies of ID cards and important documents should be copied at the time of use. There is no need to carry one with you. Remember to destroy it after use. If you make too many copies, you must put them away. Don't put them anywhere in case you steal them.

When you give your ID card and important copies to others, you should mark the copies. The more detailed the purpose of marking, the better. Generally write three lines: only XXXXX———— (Write the location and unit here, etc. ), and handle XXXXX—————— (Write the purpose here, such as credit card, etc. If he uses it, it will be invalid.
