Small access keycard able to fit into wallet for safekeeping.
Earlier versions of the badge (used to identify Troop members to one another) include tattoos, regular keys, uniform haircuts and passwords ('Open Sesame' was one password that was, unfortunately, overused). Current version of the Troop Badge includes a bio-algorythmic encryption processor within the keycard for maximum security.
Issued to all Troop member for entrance to their respective secret headquarters. Felix Garcia of the Lakewood, USA Troop discovered that it was also highly useful for wedging out batteries. Standard issue.
