The concept of this is a business card that can stay on a desk as long as it can before getting tucked away into a business card book.
(Sorry, the email address and phone number on the card are for those who have contacted me via [this email].)

If it stands, it will probably stay on the desk for some time not buried under other stuff. But if it can be used as a tool, it’ll stick around much longer. So I made it a built-in webcam cover that can be hung on top of a computer monitor (with a camera). I heard a webcam can be hacked, so it can be a precaution.
