Imagine all the theft-stopping power of car alarms, only crammed into your pocket. Of course, the No Touch Alarm Card also comes with everything you hate about car alarms: set to sound off when exposed to any amount of light, it doesn't distinguish between who pulls your wallet out of your pocket. Of course, there's no volume control. So it kind of works. Verdict? Just put your wallet in your shoe, and go take some karate lessons.
