I use the Road ID most of the time. All they tell you to put on the Road ID is name, age, contact numbers, where you're from (just city/state), and any allergies or NKDA. Then if you have room put the blood type. It will expidite the process of finding out blood type, but it doesn't take long if it's not on there.
If you put age as a birth year you don't have to update it yearly.
