I've only had my rx for a month, and its a piece of paper. I was informed that a "card" would put your name on a registration list, and if you ever wanted to purchase a handgun in the state you would be unable to do so. Other than that, any "card" isn't going to do much more for you than a regular piece of paper will.

I just tonight went and signed up as a patient at a club that was new to me, and they were able to verify my patient status via the internet. I asked if they saw my name, and they said no, that there was a # on the rx that validated the authenticity of the rx, but there was no name attached to it, other than the prescribing dr's. /hth
