Description:First of all, we have to power the circuit by a 3.7v lithium polymer battery which is rechargeable. The battery is connected to a charging circuit which helps is charging the battery as well as it sends the voltage to the LDR module for powering it up. When we connect the pin which connects the positive terminal of the battery to the positive terminal of the sensor, the module gets it’s power, where the battery’s negative terminal is already connected with the sensor’s negative terminal. Now getting to know about the connection of buzzer, the buzzers positive terminal is connected to the positive terminal of the sensor and the negative terminal is connected to DO pin which is known as the digital out pin. After adjusting the threshold voltage knob the device is ready to use. The buzzer will ring whenever there is light around it and get diffused whenever there is insufficient of light. Now this complete setup is been placed inside a wallet where we have extended the connection for LRD sensor with the module. The sensor is attached at the bottom of the wallet. So that is doesn’t get any light inside the pocket and prevent it from ringing. but whenever it comes out of our pocket it will start ringing resulting in an alert.
Although the present invention has been described keeping in contention with the description given above and the diagrams attached to this document certain changes can be made owing to new ideas and methods. These will be incorporated from time to time to make our invention as feasible as possible solving real life problems.

Claims:We claim –
1. An Anti-Theft Wallet which uses LDR and Buzzer to alert a person from pick pocket.
2. A method as claimed in claim 1, this wallet uses LDR
3. A method as claimed in claim 1, this wallet does not create any radio interference.
4. A method as claimed in claim 1, increasing the voltage above the mentioned requirement can damage the wallet.
5. A method as claimed in claim 1, this wallet does not create any harmful effect on our body nor on any one around that wallet.
6. A method as claimed in claim 1, the electrical parts are not water proof, but yes it can made waterproof in future upgrade.
7. A method as claimed in claim 1, this wallet is safe and suitable for all conditions.
8. A method as claimed in claim 1, this wallet should be kept away from fire.
9. A method as claimed in claim 1, this wallet can be made more compact in future with nano technology.
