The Gold Codes are the nuclear launch codes that are purportedly provided to the President of the United States of America in his role as Commander-in-Chief. Prepared by the National Security Agency, the code sequence is printed on a plastic card, nicknamed "the biscuit", which is similar to a credit card, that the President carries on his person. The concept behind the codes is that they permit the President to positively identify himself as the commander-in-chief and thereby authenticate a launch order to the National Military Command Center (NMCC). Should a launch situation arise, the codes would be transmitted to the NMCC.
