Abstract
A pickpocket protective wallet includes a wallet body and a DC-power-supply-operated alarm device fastened within the wallet body. A normally closed control switch turns on a sound generating circuit, causing it to produce an audio alarm signal. The control switch is opened as the wallet is put in a pocket, causing the sound generating circuit to stop working. The control switch is closed as the wallet is being taken out of the pocket, causing the sound generating circuit to turn on.
