Here's what's on our yellow laminated helmet tags at the fire department.
These are used to identify us if we're incapacitated in the fire. It's actually more than we need to notify next of kin and all that.

Name
Department (you won't need that)
Home Phone
Emergency Contact Name (don't care WHO it is or relationship)
Emergency Contact Phones (up to 3) (we can track ANY US and Canada number back to an address - including cell phone numbers)
Blood Type
Normal Blood Pressure
Normal Pulse
Allergies
Medical Conditions
Medications Taken Daily


Contrary to popular belief, us emergency workers will actually provide medical care for people that dont' have insurance! Really! Why me and Paul (another fireman) did CPR on a woman in cardiac arrest and not once did we stop to check for her medical insurance card.

All the rest of your suggested items are nothing more than an identity theft kit and are NOT needed in an emergency.
