Medical Emergency Information I.D. card..................

I am working on designing a 'calling card' for myself to give to other people that I meet that includes general information I wish to share as it is increasingly more difficult for me to communicate verbally.

A 'calling card' can be  VERY helpful to those of us with ALS and other medical conditions.....

BUT...

I am thinking it may not hurt to have a separate identification card that I  can carry upon my person to show to other people.....that contains more pertinent information (beyond just a list of current medications)... related to medical issues...
This would be in addition to the medical information bracelet that I already have.  
The cards would be good for my family members to carry...in case we are together when a medical emergency may occur  and I cannot communicate .
...something for them to have handy to present to the medical provider etc. when it may become difficult to pass along information due to stress etc..

Here is a website I found quite helpful:

an example of a medical emergency I.D. card>

I like the idea that I can have personalized cards made like a business card....
with the information I want on it 
as well as being able to pick a decorative style / design that is appealing to look at as well.....
