打印出来和真实身份证一样大吗？Will the print match the real card size?

为什么要加水印？写什么比较好？Why add a watermark, and what should it say?
身份证复印件被挪用的风险很高，建议写明用途、对象和日期，例如“仅供办理××银行开户使用 2026.10.30 他用无效”。水印覆盖在证件上，不影响识别信息，又能防止被拿去办其它业务。ID copies are often misused. State the purpose, recipient and date — e.g. “For XX Bank account opening only, 2026-10-30”. It overlays the card without hiding the details but blocks reuse.

尽量把证件放在深色桌面上正对着拍。照片方向不对时点“旋转”；证件在照片里只占一部分时，拖动蓝色框框选证件即可。Shoot the card straight on against a dark surface. Use Rotate if it is sideways, and drag the blue frame to select just the card.
