I would start with a business/office machine store or company. Check with one who supplies machines to hospitals.Originally Posted by Marc Veeneman
At the psych hospital I worked at, whenver someone was admitted our computer would send the info to a "card imprinter machine" (don't know the exact name of the machine) that would imprint the info onto credit card sized plastic cards. They were just like credit cards, but without a magnetic strip. We would get boxes of the blank cards from the same place we got the machine.
After reading the above idea, these cards would be PERFECT for something like this. They were shiny on one side, and matte on the other, and you can get them in different colors. Don't know how expensive they were.
Hope this helps!
