Can organ donation cards be sent to friends?

If it were me, I would send it. If donating this useless body will bring more hope to several unfortunate poor people, then I will definitely be more willing to help others while I am alive, so I will register my body donation. This is my motive. Because it will let others except me know that I have done something beneficial to others, and then I will be more happy and glad that someone knows that I have done something good. If the bystander is very concerned about what happens after death, then he will admire me two more things; If that person doesn't care about the world after death as much as I do, then he should also understand my thoughts. What a sacred thing this is. I don't think anyone will be cynical. If there is, it can be regarded as a filter for people in the circle of friends, so that you can see some people more truly. Moreover, after seeing your circle of friends, people who share your thoughts may also have the idea of donating the body. Then, there will be a few unfortunate people in this world who are less painful and brighter.
