Vivre Card

Biblicards (ビブリカード biburikādo, also known as Vivre card), also known as "the paper of life", are a special form of paper made in the New World. A Biblicard is made from part of a person’s fingernail which is then made into paper. It is completely waterproof and fire proof but can be torn and given to someone you care about if you are to be separated. The torn piece will point you to the person the Biblicard was made from by moving in their direction. However, if a Biblicard begins to burn on its own that means that the life of the person who gave the Biblicard is vanishing.

Biblicards Received by Straw Hats

 * Portgas D. Ace: The very first Biblicard received in Arabasta to help Luffy find his brother. It has diminished quite significantly due to Ace being captured and in danger of execution.
 * Lola's Momma: Received from Lola of the Rolling Pirates, she gives Nami a Biblicard of her "momma" in case they need her assistance in the New World.
 * Silvers Rayleigh: After the trouble they caused on the Sabaody Archipelago, Rayleigh gives each member of the Straw Hats Crew a Biblicard to find him once their ship has been coated.
