ABSTRACT:
A wallet is disclosed in which a theft prevention device is installed. If the wallet departs from the pocket, a melody is generated so that the owner can recognize the departure of the wallet from the pocket, thereby preventing the theft of the wallet. An oscillation plate is installed between the outer cover and the inner layer of the wallet, and a photo sensor is installed to respond to the visible light so as to activate the oscillation plate. Further a manual switch is installed to make it possible to turn the power source on or off.
