I am looking for a machine that will cut the corner off of plastic playing cards?

I don't know of a machine, but you can get a handheld punch that rounds off corners. Look for it in the section of your craft store that has the punches. It's usually close to the scrap booking section. I've used it, and it does a good job.

Use a paper cutter.
