I have the roadid the dogtag style. Mine has the Aussie flag on the back. This way if I ever need medical aid they wont think Im talking gibberish because of any injury. You might laugh but when I got stuck with a car problem and had to use AAA the lady on the phone informed me that she just could not understand what I was saying. It took ages just to get the address I was at correct. Who would have thought having an Aussie accent would have caused so much trouble.
The most effective way to do it, is to do it.
