1. Remember to endorse your ID card when sending it to others or institutions. The writing method is divided into three lines, with a blue ballpoint pen. Some strokes will cross or touch the words on your ID card, so be sure to draw a horizontal line after each line to avoid being added with other words.
Please indicate the purpose of this copy next to it. As a statement. For example, "this ID card is only used for XXXX, and other purposes are invalid" and so on.
3. Credit cards, funds, mobile phones, applications, as long as you need a copy of your ID card, and so do government forms.
