I decided to do this project because I felt I had a few security vulnerabilities with respect to my vehicle. There are plenty of things I can do to perhaps prevent an attack on myself in my vehicle. That is a fool-hearty goal at best. Prevention of any crime is difficult to measure. We assume crime is prevented by the things we do but we have no idea as to whether the threat ever went away. Our best course of action, then, is to think about mitigation. In other words, we seldom plan for WHEN the attack or emergency will occur. In this scenario, I felt I a great mitigator would be the use of a discreet mechanism alerting authorities and other concerned persons if I found myself in an emergency. I felt NFC (near field communication) tags would be best, since my phone is an integral part of my travels in my vehicle. Placement of course was key, so I positioned the tag just below where I keep another tag that commands my phone to turn on my map an increase its brightness. The duress tag alerts the authorities and tweets out a duress message to friends and followers on social media. As you can see from the video it is place in a way where I can't accidentally activate the duress command. Imagine a scenario where the phone is mounted on the phone holder while I'm carjacked. The bad guy asks for the phone and I have an opportunity to grab the phone and place it on the tag for a second to activate my duress. I stall the attacker until the authorities arrive. I set the phone to activate the duress with the screen locked out when activated with no speakers on and only the microphone working.
Here is the pic of where my tags are located inside my vehicle:

A couple of great links to where you can buy some tags.

There are also a number of apps to use. I use Trigger. See the link below to download it from the Google Play Store:

The thing about NFC tags is they are very inexpensive and relatively easy to implement. Almost a perfect security tool when properly used.
