Binding of Isaac: Rebirth Wiki

Added in Repentance

Member Card is an unlockable passive item added in The Binding of Isaac: Repentance.



  • The trapdoor spawns even if the shop was replaced by Greed Greed or Super Greed Super Greed, in which case it won't open until Greed has been defeated.
  • Similar to Crawl Space Crawl Spaces, there is only one secret shop per floor. The trapdoors in extra shops created by Red Key Red Key will lead to the same secret shop.
  • If the Member Card was removed from the player's inventory (for example, by playing Tainted Isaac Tainted Isaac and replacing it with a different item), the trapdoor will still remain open once it has been spawned, even after leaving and reentering the shop.
  • The trapdoor will appear in the Mirrored World version of the shop. Despite the shop itself being empty, the trapdoor will lead to the same secret shop where the items are still for sale. Buying from the secret shop in the Mirrored World will thus remove the bought item from both worlds.
