Is probably research. First test what happens when you have exclusive payment areas for a limited time and see if anyone kicks off really badly and if the fallout from doing so costs more money than what you make. If not, roll out to more events to try and establish a new standard practice, while keeping a very close eye on social indicators and the bottom line.
Since Visa's been doing this since 1986, that's an awfully long test. They do quantify the results, though:
> According to the U.S. Sponsorship Tracker, a Visa commissioned study following the Vancouver 2010 Olympic Winter Games conducted by Performance Research, an independent research company, Visa cardholders
who were aware of Visa’s Olympic Games sponsorship claimed a 16 percent and nine percent increase in Visa card usage in Canada and the US respectively. The same report found Visa’s brand equity was 32 percent and 38 percent higher among consumers who were aware of Visa’s sponsorship in Canada
and the US respectively.
OK. Fair enough. They haven't just miraculously turned into complete bastards on this, they were just complete bastards all along and the press happens to be making a fuss about it at the moment, just cos it is news with the word 'olympics' in it.
Just because consumers accepted something in the past does not mean they will accept it in the future.
For example, in the past when I found a flashy new b2b service I would grumble when I couldn't find a price list and continue my research. Now, when I visit a company's page and there are no listed prices, I immediately close the tab and forget about it.
Saying "We only accept Visa" is like saying "We only serve white people." Exclusive, yes. A reminder of ethnic and class privilege, yes. Desirable by any progressively minded individuals? Absolutely not.
A note about online payments when it comes to credit cards, I pretty much stopped using my Mastercards with the exception of Amazon because of that damn Securecode implementation. I think payment processors and providers who erect any restrictions or barriers will find them self quickly suffocated out by services who are going the other direction. (I'm one of the guys who believes within the next 5 years you'll just be able to walk out of most stores with a product and seamlessly be billed for it, uber style.)
