Can Anyone Read Holed Key Cards?

I posted this on the SlotCard BBS, also.

I was just wondering if anyone knows how to read the holes in older punched key cards such as these. I have some that I am pretty sure I got while staying at Resorts many years ago. But they do not have any identifying information. It occurred to me that perhaps the Casino Hotel name is coded in the holes. Can anyone read these holes?
Thanks--Alan.
