Hello, taking banking business as an example, mark the purpose on the copy of the ID card, usually written in 3 lines: only XX bank - apply for a credit card - invalid for other uses - each line Be sure to draw a horizontal line at the end to avoid being added accidentally.

For safety and reliability, the ID card copy can be marked as follows: ① Write "XX" on the ID card copy, be as detailed as possible, and do not cover the ID number and name, ② Some strokes and identity The words on the ID card must intersect or touch each other.

Precautions for using the ID card 1. Take good care of your ID card to prevent loss. It is best not to lend it to others. If you ask others to do things for you, you should also entrust it to someone you trust. 2. Keep a copy of your ID card.
