Medical ID necklace? - medical necklace

Hello I am 17 years old and I'm going to suffer a music festival at the weekend and from heart disease and must remain drug percific if someone comes to me. In thinking, get a medical ID chain to be on the safe side .. but all I can find dog tags that are recorded on .. But I have these chains, a pipe at the end of the screw and the role of a piece of paper in which they have seen with their medical home, Can you please tell me what I can to the side to find them? Thank you very helpful

George.
