Ever wonder how car alarms deter criminals from stealing your favorite vehicle from your driveway? It’s because the alarms signal the owner of the car to call the police; then come out with a baseball bat and beat the living daylights out of the thief. The Alarm Card does the same. It is made up of material that, when exposed to light, emits a loud sound to notify its owner that his or her bag is being opened. Place it in your wallet to achieve the same results. Think of all the time you will save running after these bad elements when you catch them in the act. Now that is swift justice!
