Paper that converts trust into math, right up until it expires or you forgot to renew it.

means An official document that formally attests to a fact, qualification, or achievement.

from From Latin 'certificare' — to make certain — built from 'certus' (certain, sure) plus 'facere' (to make). It passed through French 'certificat' before landing in English in the 15th century, carrying the same job the whole way: taking something true and putting it in writing so nobody can argue with it.
