Hispanic/Brazillian CPS2/3 quirks

A couple of members from the Neo-Geo.com boards have noticed on hispanic and Brazillian CPS2 and 3 versions of games, there’s an option for C.DISPENSER, which when set to ON, puts “NO CARD” on the screen. What’s the deal? Is it just some sort of payment method that was popular/mandated?

Could be, When I was in morelia they have this card system that you put money onto.

I think this has something to do with taking card swipes as credit instead of quarters? So yeah, probably an alternative payment method.
