A secret decoder ring (or secret decoder) is a device which allows one to decode a simple substitution cipher - or to encrypt a message by working in the opposite direction.
As inexpensive toys, they have been often used as promotional items by retailers, radio and television programs from the 1930s through to the current day. Decoders, whether badges or rings, are a fun way for children to tap into a common fascination with encryption, ciphers, and secret codes, and are used to send hidden messages back and forth to one another.

Famous quotes containing the words secret and/or ring:
“We all have bad days, of course, a secret that only makes us feel more guilty. But once my friends and I started telling the truth about how far we deviated from perfection, we couldn’t stop. . . . One mother admitted leaving the grocery store without her kids—”I just forgot them. The manager found them in the frozen foods aisle, eating Eskimo Pies.””
—Mary Kay Blakely (20th century)
“But whatever happens, wherever the scene is laid, somebody, somewhere, will quietly set out—somebody has already set out, somebody still rather far away is buying a ticket, is boarding a bus, a ship, a plane, has landed, is walking toward a million photographers, and presently he will ring at my door—a bigger, more respectable, more competent Gradus.”
—Vladimir Nabokov (1899–1977)
