Apart from the fake Galleons enchanted by Hermione for Dumbledore's Army, there are a few other methods of closed-channel communications used in the books and films. Subjects painted into wizarding portraits are frequently used to carry messages between locations where their portraits hang. Phineas Nigellus (former Hogwarts headmaster and member of the Black Family) is used to send messages between Dumbledore's office and his other portrait in Grimmauld Place. Hermione takes Phineas from Grimmauld Place during "Harry Potter and the Deathly Hallows" and uses Phineas to obtain information about events at Hogwarts. Dumbledore also uses two other former headmasters in a similar fashion when Arthur Weasley is attacked by Nagini in the Ministry of Magic. A portrait is also seen carrying messages between the Minister for Magic and the Muggle Prime Minister in the opening of "Harry Potter and the Half-Blood Prince".
