Design And Construction Of An Anti-Pickpocket Alarm

ABSTRACT

This is a security device for alerting an individual that their wallet or the like device has been stolen from their person includes a housing containing an alarm concealed within the wallet and tethered to the individual or another article being carried. The wallet alarm sounds when the wallet is removed far enough to tighten and disconnect the tether from the wallet. This action activates the alarm.

CHAPTER ONE

1.0                                                        INTRODUCTION

The increasing use of credit cards has instilled new vigor into the ancient craft of pickpocketing, as the theft of one’s purse or wallet, with its typical assortment of such cards can produce hundreds and even thousands of dollars in ill-gotten gains. This is particularly true if the loss of one’s wallet is not detected immediately, giving the thief/thieves time to run up expensive charges before the cards can be invalidated by their owner.

Any successful theft deterrent device to be worn on a person’s body or carried in a purse must operate under guidelines which anticipate a pickpocket’s methods and his behavior if caught in the act or apprehended.

Pickpockets frequently work in teams of two or more individuals. The least complex, a two-man team, consists of a “stall” who intentionally attracts a would-be victim’s attention while a second individual, a “pick”, actually removes an article from the victim’s clothing or purse. Skillfully done, the victim will not notice the theft immediately, giving the thieves an opportunity to disappear. In some cases, teams of three or more cooperate to pass the stolen article from one to another, thus further escaping detection.

Aside from detection, no pickpocket wants a confrontation with a victim. Being caught in the act, in close proximity to his victim, may panic a pickpocket, causing him to react violently in an attempt to escape. This is particularly true of alarms carried by the victim, which go off when a thief is in body contact with his victim.

1.2                                    AIM OF THE PROJECT

The main objective of this work is to design an alarm which is actuated when a wallet is removed from a person.

1.3                             OBJECTIVE OF THE PROJECT

At the end of this work, students involved will be able to:

1. Provide an improved portable security system to prevent a wallet being stolen from a person’s pocket or purse.
2. To provide a pickpocket alarm which operates in such a manner as to anticipate the behavior of a pickpocket so as to most effectively recover the stolen item with minimum danger to the victim, while attracting attention to the thief to aid in his capture.

• Provide a first alarm which is installed in a person’s wallet and which is activated when the wallet is removed but at a distance from either the victim’s person or his/her purse.

1.4                                         SIGNIFICANCE OF THE PROJECT

This can be a problem if a pickpocket removes your wallet and quickly hides it away once they steal it. This portable alarm set off when the wallet is removed from the victim’s pocket. This device had made pick-pocketing to reduce, in that thieves are now afraid of been caught because it is very portable that one cannot know who is using it or not

1.5                                           LIMITATION OF THE PROJECT

Devices of the above type all suffer from a common shortcoming. The wearer of the device is alerted when the thief is close at hand, probably within physical contact range.

1.6                                          APPLICATION OF THE PROJECT

This device can be used by:

• Pedestrian – when going to crowdy areas such as school, markets, cinema etc
• Cyclist and drivers – when driving their passengers
