That pdf is a legit card. I have an actual card given to me by a hospital worker friend of mine and it matches exactly. The card is printed on thick-ish card stock not thin regular “copy paper.” It’s on a card stock that would be equivalent to a wedding announcement. They have the paper at the copy centers at Office Depot or Staples. Just get a dozen or so pieces of paper and print them at home. Lining up the front and back may be slightly difficult.

Then, have it laminated. And also put it in one of those lanyards mentioned above and you won’t be able to tell the difference.
