How to put the bank card on the mobile phone desktop

The bank card is placed on the desktop of the mobile phone. You can only take pictures of the front and back of the bank card with the camera, and then use the built-in editing function of the camera to set it as the wallpaper of the mobile phone, but this is very unsafe. If someone gets your mobile phone, you can see the information of your bank card soon. It is recommended that you set a password or fingerprint unlock or line password on your mobile phone. Be sure to set it up.
