abbreviating your masters? MSF? MS? MS-Fin? either, especially, business, finance, people

For those of you with a masters in finance - how do you abbreviate it for business cards, etc ? They all seem to be either unrecognizable or too long. I've seen some people just leave it off, especially if they have a CFA, but i don't really get why you wouldn't want to advertise your masters.
