Access to the machine — the Sarco capsule — will be by completing an online questionnaire, which produces a four-digit access code. On reclining in the capsule, activation uses liquid nitrogen to rapidly drop the oxygen level, and a peaceful death will result in just a few minutes. The capsule can then be detached from the Sarco machine and used as a coffin. The machine base can be reused.
Sarco does not use any restricted drugs or require any special expertise such as the insertion of an intravenous needle. Anyone who can pass the entry test can enter the machine and legally end their life.
