It is not electronic. If it showed up as "shipped" 3 months ago, I would suggest calling the Marriott Rewards customer service number and ask about it.

I gave mine away right after I received it, so I can't help much on the fine print side of things except to say that I do believe it is limited to certain golf courses. I would guess that they would normally be printed on a quarterly basis and that they expire about 6 months from the end of that quarter. So you should normally have about 6 months or so to use it. Since I was able to give mine away, I don't think you have to be there for its use. You can gift it to anyone and they can use it.
