 FACT: The security at the gold vault at the Federal Reserve is  incredibly low tech and is impossible to hack into either via  computer or through a wall. Located many stories even below the  subway, the only way in or out of the vault is through a ten foot  corridor which is rotated at night, sealing the vault. (As a note,  there is only a 72 hour air supply once the vault is sealed.) (This  information is online at the banks web site, so its no secret.)
