A red box is a phreaking device that generates tones to simulate inserting coins in pay phones, thus fooling the system into completing free calls. In the United States, a nickel is represented by one tone, a dime by two, and a quarter by a set of 5 tones. Any device capable of playing back recorded sounds can potentially be used as a red box. Commonly used devices include modified Radio Shack tone dialers, personal MP3 players, and audio-recording greeting cards.
Famous quotes containing the words red and/or box:
“The Red Cross in its nature, it aims and purposes, and consequently, its methods, is unlike any other organization in the country. It is an organization of physical action, of instantaneous action, at the spur of the moment; it cannot await the ordinary deliberation of organized bodies if it would be of use to suffering humanity, ... [ellipsis in original] it has by its nature a field of its own.”
—Clara Barton (1821–1912)
“You’re the most beautiful woman I’ve ever painted. Not because you’re beautiful but because I’m in love with you. Hopelessly in love with you.”
—Muriel Box (b. 1905)
