So I'm making an emergency card that I will carry in my wallet. What would you include on an emergency card that you carry with you at all times?

I'm making this emergency card with the person that comes upon my unconscious body (due to an accident, illness, etc.) in mind. I want to put as much clear information as possible on this card. As a secondary use I plan to use it in place of an address or contacts book.

The card is the size of a standard credit card.
What do you think of what I'm including?

Emergency contacts grouped by household i.e. My Household, My In-Laws' Household
The Emergency Contacts will have their:
-First and Last Names
-Association to me
-Home, Work and/or Cell phone numbers
-Address

Health Insurance information including:
-The Name of the health insurance company
-Toll free number for the health insurance company
-ID #
-Group #
-Bin # (whatever that is)

Pre-Paid Phone card information including:
-The Toll Free Access Number
-PIN Number
-Customer Service Number
-Toll Free Access Number for use in Mexico
-Toll Free Access Number for use in Canada
This Pre Paid Phone card information will be disguised on the card so no one, but myself will know what it is or how to use it.

Vital information about my family:
-Blood Types
-Allergies
-Medical Conditions
-Medications
-Social Security Numbers and Birth Dates (these will be located somewhere else on the card and disguised so no one, but my family and I can read them)

Measuring Increments... Like a ruler...You know, for measuring.

How much is too much information? If this card were lost or stolen... What information should not be included for the safety and security of the contacts included on the card (or even myself)?

So far with all that I still have the entire back of the card blank. What other information should be included?
Religious preference? (for burial purposes)
Moris Code Legend?
My wife's secret Thanksgiving turkey recipe?


I've even been considering the card's physical make up too.
I was thinking of printing it on yellow or orange fluorescent paper. But that might be hard for a person to read.

I was also considering laminating it with a plastic that is easy to write on with pencil or erasable ink pen. I don't know why, but I was thinking the card could also be written on and then erased if needed.


Any input?
Thanks

/edit forgot to mention I'm including the last time the card was updated. That way anyone that reads the card will know how current the information is.
