I wear my "interactive" RoadID (where they can call in for my health and contact information) and copies of my drivers license and health insurance card. I am just afraid of losing them which is why I carry copies and not the actual cards/paper.

I need another RoadID band though, it keeps coming unattached - this is the velcro version. Thinking about the rubberized version eventually. The velcro only comes unattached when I am taking my Camelbak on/off, the problem is I don't always notice it when it happens
