A doctor gives you a recommendation on paper, with a pic of your driver license. This is also know as a certificate. This rec, and your ID is all you absolutely NEED to have.

The card is either a card from a particular club that requires it for entrance. This is totally voluntary, and the club can set their own rules after adhering to state requirements. If a club requires something more than your ID and recommendation, then you can always go to another club. If you are new to a club, they will always verify your recommendation, and this can be a good wait if you have a rec from a private doctor, as they must contact them to verify. Places like Medicann are more accessible, and make it easier to verify your rec.

1. The OCBC card referred to is also voluntary. But in this area, clubs, especially San Fran proper, require this for entry. It's just a way to get into the club quickly. Being able to visit those clubs makes it worth the 30 bucks for the card. But remember, it's voluntary.

2. The state ID card is a different thing altogether. This is the state trying to implement a specific standard for regulating the sale of medical marijuana. There are pros and cons to this. Many think it's a great idea. But for me, I don't like it a bit. It's just another way to keep track of medical marijuana patients.
Again, this is supposed to be voluntary, so don't let anyone tell you otherwise. For those clubs that require it, I do not visit their club. Since it is supposed to be voluntary, I volunteer to not participate.

Prices vary for the state ID card, and you must apply at your county health department. I have seen these for 60 dollars and up. They are raising the prices through the roof because not enough people are registering for them. Hmmmm...wonder why.

I hope this has answered your original question.

Peace and happiness
