FINAL REPORT

Project Proposal Guideline

1. Introduction
   
   
   
   1. Statement of Purpose
      
      The purpose of this project is to remind users when their credit card is left behind and to prevent theft.
      
      
   2. Background Research
      
      Cards are left behind all the time, without users realizing. Although people can suspend their credit card temporarily, the only occurs after the loss. This will prevent the issue outright. In addition the extended project will take it a step further and immediately protect the card.
      
      
2. Design Details

   2. System Overview
      When the system is running, on the arduino side, it will constantly send the Bluetooth signal strength to the phone. And when the signal strength is below a certain threshold, which indicates that the distance between the card and the phone is abnormal, the Bluetooth module on the arduino will start sending GPS coordinates until the signal strength goes back to normal. 
      On the phone side, it will display the text notifications regarding the Bluetooth signal strength all the time. And when the signal strength goes below the threshold, the phone will receive both text and sound notifications and visualized directions to help find the card (the directions would be calculated by comparing the GPS coordinates of the phone and the senor on the card).
      
      Battery powers both the arduino, the bluetooth module, which then communicates with the phone, and the GPS module. The Bluetooth signal strength and GPS coordinates will be sent through Bluetooth to determine distance and guide finding. 
      LEDs will be used to debug any issues (Bluetooth AND GPS = LED)

   List all references you used in your proposal. This is important, you do not want to be blamed for plagiarism. IEEE citation format is highly recommended. You can use citethisforme.com's IEEE citation generator to painlessly generate your references in this style.
3. Extended Project
   1. If time permits, an electromagnet will be implemented to prevent the card from being used until the user deactivates the the interference field.
