Cryonics is the preservation at very low temperatures of bodies or body parts after death. It is used by people who hope that future medical science will be able to restore them to life, and find cures for any medical conditions they may have. This card authorises Alcor Life Extension Foundation to carry out cryonic suspension. The other side gives instructions to medical teams about what to do to ensure the best preservation possible is achieved. The card is shown here with two other ways to communicate a person’s wishes after death, a necklace (1999-783) and a bracelet (1999-784).
