Badges are Key Items in Bloodborne.

Description
Badges are items that, though may seem worthless at first glance, actually hold a sort of value to the Messengers. Specifically the Bath Messengers, who will promptly expand their wares, allowing players to purchase items that are connected to the group that each specific badge belongs to.
Badges can be found in specific locations, are dropped by enemies/bosses in the game upon death, and can even be awarded by killing NPCs or completing their quests.
