More commonly know as ICE, there are a number of solutions to make carrying this data easier and therefore less likely to be forgotten.
If you have a smart phone that you take on your rides, consider setting your main lock screen to display these details. That way someone can see without having to know the pin-code. One iPhone app that makes this very easy is Ride ID, Android options also exist.
There are a number of wrist bands that can be bought with ICE details embossed, see http://www.roadid.com/ for an example.
Or simply print out the details, laminate and leave in your saddle bag. This site gives a useful template to use http://geticecard.com/
